Of course, seasonal allergies, frightful weather and wildfires can all conspire to make open windows impossible. Air purifiers are your second best option. With sound-muffled fans and multi-layered filters, these simple machines can clear up odors, cooking emissions, dust particles, smoke, pet dander and more. We performed simple at-home tests to compare different models, mostly focusing on smart models with app control and auto modes. We compared the features, designs and prices to help you find the best air purifier for your home.<\/p>\n<div class=\"commerce col-body\">\n<div class=\"mb-8 mt-4 dark:text-grey-hair\">\n<div

Core 400S Smart Air Purifier isn\u2019t trying to be anything fancy. It\u2019s a simple white cylinder with holes for air intake and a black ring of vents on top. Touch controls in the center of the vents are easy to suss out, letting you adjust the fan speed, enable auto mode and turn on a sleep setting, which drops the fan to the lowest intensity and shuts off the display lights. The internal sensor measures particulate matter at 2.5 microns, which displays in the center of a lighted ring near the controls. The ring turns blue when all is well and moves through to green, orange and red as air quality levels deteriorate. In auto mode, when it detects a drop in air quality, the fan increases speed until levels go back down.<\/p>\n<p>Even at its highest level, the fan isn\u2019t terribly loud, peaking at around 62 in the Decibel Meter app and leaving my cat undisturbed on the couch nearby. Yet the force of the air coming out is strong and feels on par with output from purifiers that are quite noisy (which made the cat run away).<\/p>\n<p>The Core 400S claims a half-hour air exchange rate for a 1,000-square-foot room and combines the three main filter types \u2014 pre-filter, activated carbon and HEPA \u2014 into a single ring. Perhaps the best part is a replacement filter is only $50, half the price of some competing brands. In multiple burn tests, the Core 400S reliably got the room back to its starting level in about a half hour of running on high. Auto mode does a good job of reacting to drops in quality, kicking on to a higher fan level nearly every time someone in the house cooks and after an incense burn.<\/p>\n<p>This true HEPA air purifier connects to the VeSync app; setup is easy, but the app itself is overpacked. There\u2019s a forum, a wellness tab and a shopping page where you can buy not just Levoit products, but also devices from sister brands Etekcity and others. But as far as controlling the Core 400S itself, the in-app controls are easy to use and nicely laid out.<\/p>\n<\/div>\n<div class=\"flex flex-col rounded-lg bg-marshmallow p-5 @xl\/p:flex-row dark:bg-batcave clear-right mb-5\">\n<div class=\"flex-1 border-solid border-dirty-seagull dark:border-charcoal border-b @xl\/p:border-b-0 @xl\/p:border-r-2 mb-6 mr-0 pb-6 pr-0 @xl\/p:mb-0 @xl\/p:mr-4 @xl\/p:pb-0 @xl\/p:pr-4\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Pros<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Easy on-board controls<\/li>\n<li class=\"list-disc\">Reliably improved the air quality in our tests<\/li>\n<li class=\"list-disc\">Inexpensive replacement filters<\/li>\n<li class=\"list-disc\">High speed is powerful, but not overly loud<\/li>\n<\/ul>\n<\/div>\n<div class=\"flex-1\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Cons<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">The companion app is over-stuffed<\/li>\n<li class=\"list-disc\">Ho-hum design<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>$200 at Amazon<\/p><\/div>\n<\/div>\n<\/div>\n<div class=\"commerce productModule [&amp;+.productModule]:mt-9 [&amp;+.productModule]:border-t [&amp;+.productModule]:border-dirty-seagull [&amp;+.productModule]:pt-2 [&amp;+:not(.productModule)]:mt-10 col-body\" id=\"257983fed5ef4b9091b950d00337aac7\">\n<div class=\"mt-6 text-batcave @container\/p dark:text-grey-hair\">\n<div class=\"block\">\n<div class=\"relative mb-4 w-full overflow-hidden rounded-lg border border-grey-hair pb-[75%] @xl\/p:pb-[56.25%]\"><img decoding=\"async\" alt=\"Image for the large product module\" class=\"mx-auto my-0 size-full bg-white object-contain @xl\/p:transition-transform @xl\/p:duration-300 @xl\/p:ease-in-out @xl\/p:group-hover:scale-110 @xl\/p:motion-reduce:group-hover:transition-none\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2025\/12\/acece0d0-b8d7-11f0-bd7f-8addfce0ff3e-1.jpg\" loading=\"lazy\" height=\"720\" width=\"1280\" title=\"acece0d0-b8d7-11f0-bd7f-8addfce0ff3e-1\"><\/p>\n<p class=\"absolute -right-0.5 bottom-0 rounded-bl-none rounded-br-lg rounded-tl-lg rounded-tr-none bg-white\/90 px-3 py-2 text-[10px]\/3 text-battleship\">Amy Skorheim for Engadget<\/p>\n<\/div>\n<div class=\"mx-0 my-auto overflow-visible @xl\/p:grow\">\n<div class>\n<h3 class=\"mb-1 text-xl\/[1.3] font-bold @xl\/p:text-2xl\/tight\">Best premium air purifier<\/h3>\n<h4 class=\"m-0 text-lg\/6 font-bold\">IQAir Atem Earth air purifier<\/h4>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"commerce-desc mb-5 mt-2 space-y-6 text-base\/relaxed md:text-lg\/8 [&amp;_li]:ml-4 [&amp;_ol&gt;li]:list-decimal [&amp;_ol]:space-y-6 [&amp;_ul&gt;li]:list-disc [&amp;_ul]:space-y-6\">\n<p><strong>Filters<\/strong>: Activated carbon, HyperHEPA | <strong>Auto Mode<\/strong>: Yes | <strong>App-connected<\/strong>: Yes | <strong>Sleep Mode<\/strong>: Yes | <strong>Coverage area in 30 minutes<\/strong>: 1,460 sq.ft. | <strong>Max decibels<\/strong>: 63 | <strong>Weight<\/strong>: 17.2 lbs | <strong>Filter replacements<\/strong>: $100 | <strong>Filter lifespan<\/strong>: 3 &#8211; 4 years<\/p>\n<p>This is the second air purifier from IQAir that I\u2019ve tested. The first was a 35-pound, white monolith that looked like it belonged in a hospital. The performance was mid and the price tag was high; in other words, it didn\u2019t wow me. Fortunately, the brand\u2019s latest model is a dream \u2014 still a high-priced dream, but this time, more worth it.<\/p>\n<p>The <ins>IQ Air Atem Earth<\/ins> is one of the nicest looking air purifiers I\u2019ve seen. The exterior is made from slats of real, unvarnished beechwood and the redesigned filter has a frameless build to eliminate plastic from its construction (the machine still has plastic components, but the reduction is appreciated). The circular top is home to simple touch controls and a lighted ring that indicates the quality of the air, showing green for good, yellow for moderate and red for bad.<\/p>\n<p>Getting the Atem Earth set up and connected to Wi-Fi took just a few steps, and relied on a QR code found on a conveniently attached tag. The IQAir app may already be familiar to anyone with an interest in air quality \u2014 thousands of contributors share data collected by their own outdoor monitors, which you can view in the Map tab. The app also lets you control the purifier with simple remote buttons, view the detected air quality and history, and set schedules for fan modes and times.<\/p>\n<p>In my burn test, it cleaned up particulate matter quickly, getting levels to better than they were before I lit the incense. It also cleaned up the VOC levels fairly thoroughly, though it took an hour before those levels stabilized.<\/p>\n<p>I lived with it in my living room for a week or two and was impressed by how quickly the Atem Air detected disturbances in air quality. When someone started cooking or lit incense in the other room, I\u2019d hear the fan shift into higher gear. This often happened before either of my AQ monitors detected anything was amiss. I also appreciated how quickly it would drop back down to low after the smoke cleared (literally). Other purifiers I\u2019ve tested stay in reactionary mode long after the danger has passed.<\/p>\n<p>I used the purifier in Balanced auto mode (there\u2019s also Quiet and Max modes) and mostly, I forgot it was there. The lowest fan setting is inaudible and even on high it\u2019s not terribly noisy. Overall, it\u2019s just a really pleasant machine \u2014 with the only caveat being its $999 price tag.<\/p>\n<p>For that amount you do get a ten-year warranty and a 25-year repair guarantee. The plastic-free filter combines an odor-reducing carbon layer with AirIQ\u2019s HyperHEPA technology that can capture more than 99.5 percent of particles down to 0.003 microns \u2014 for comparison, a true HEPA filter must remove airborne particles as small as 0.3 microns, so this one gets deeper into the nitty gritty (again, literally). The filters cost $100, but can last from three to four years based on 12 hours of usage per day, which is longer than most other filters. If you can handle the cost and want a reliably clean air filter, this is the one to get.<\/p>\n<\/div>\n<div class=\"flex flex-col rounded-lg bg-marshmallow p-5 @xl\/p:flex-row dark:bg-batcave clear-right mb-5\">\n<div class=\"flex-1 border-solid border-dirty-seagull dark:border-charcoal border-b @xl\/p:border-b-0 @xl\/p:border-r-2 mb-6 mr-0 pb-6 pr-0 @xl\/p:mb-0 @xl\/p:mr-4 @xl\/p:pb-0 @xl\/p:pr-4\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Pros<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Attractive design relies heavier on wood than plastic<\/li>\n<li class=\"list-disc\">Accurate and powerful auto mode<\/li>\n<li class=\"list-disc\">Fairly quiet<\/li>\n<li class=\"list-disc\">App is useful for air quality monitoring<\/li>\n<li class=\"list-disc\">10-year warranty and 25-year repair guarantee<\/li>\n<\/ul>\n<\/div>\n<div class=\"flex-1\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Cons<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Expensive<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>$999 at IQAir<\/p><\/div>\n<\/div>\n<\/div>\n<div class=\"commerce productModule [&amp;+.productModule]:mt-9 [&amp;+.productModule]:border-t [&amp;+.productModule]:border-dirty-seagull [&amp;+.productModule]:pt-2 [&amp;+:not(.productModule)]:mt-10 col-body\" id=\"a3511cd8531148cfa48c757d92ee552e\">\n<div class=\"mt-6 text-batcave @container\/p dark:text-grey-hair\">\n<div class=\"block\">\n<div class=\"relative mb-4 w-full overflow-hidden rounded-lg border border-grey-hair pb-[75%] @xl\/p:pb-[56.25%]\"><img decoding=\"async\" alt=\"Image for the large product module\" class=\"mx-auto my-0 size-full bg-white object-contain @xl\/p:transition-transform @xl\/p:duration-300 @xl\/p:ease-in-out @xl\/p:group-hover:scale-110 @xl\/p:motion-reduce:group-hover:transition-none\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2025\/12\/0655e510-b8d6-11f0-bf7f-2ada44ecbe4e-1.jpg\" loading=\"lazy\" height=\"720\" width=\"1280\" title=\"0655e510-b8d6-11f0-bf7f-2ada44ecbe4e-1\"><\/p>\n<p class=\"absolute -right-0.5 bottom-0 rounded-bl-none rounded-br-lg rounded-tl-lg rounded-tr-none bg-white\/90 px-3 py-2 text-[10px]\/3 text-battleship\">Amy Skorheim for Engadget<\/p>\n<\/div>\n<div class=\"mx-0 my-auto overflow-visible @xl\/p:grow\">\n<div class>\n<h3 class=\"mb-1 text-xl\/[1.3] font-bold @xl\/p:text-2xl\/tight\">Best air purifier for small rooms<\/h3>\n<h4 class=\"m-0 text-lg\/6 font-bold\">Dyson Hushjet Purifier Compact<\/h4>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"commerce-desc mb-5 mt-2 space-y-6 text-base\/relaxed md:text-lg\/8 [&amp;_li]:ml-4 [&amp;_ol&gt;li]:list-decimal [&amp;_ol]:space-y-6 [&amp;_ul&gt;li]:list-disc [&amp;_ul]:space-y-6\">\n<p><strong>Filters<\/strong>: Activated carbon, electrostatic HEPAsilent | <strong>Auto Mode<\/strong>: Yes | <strong>App-connected<\/strong>: Yes | <strong>Sleep Mode<\/strong>: Yes | <strong>Coverage area in 30 minutes<\/strong>: 203 sq.ft. | <strong>Max decibels<\/strong>: 53 | <strong>Weight<\/strong>: 6.9 lbs | <strong>Filter replacements<\/strong>: TBA | <strong>Filter lifespan<\/strong>: 5 years HEPA, 1 year carbon<\/p>\n<p>A word of caution: If you get this, you may find yourself wondering why the <ins>HushJet<\/ins> has simply decided to turn itself off. When you hold your hand over the blue jets, you\u2019ll find that it is indeed still on \u2014 it\u2019s just gravely silent. So yes, Dyson\u2019s latest air purifier is aptly named. Even on the highest setting, the HushJet is still quieter than most other purifiers I\u2019ve tested, but the air coming out the top is forceful. But it\u2019s not only quiet \u2014 it also does a good job keeping the air clean in small spaces.<\/p>\n<p>Setup couldn\u2019t be easier: just download the Dyson app, sign in and hold your phone to the display. You can give Dyson your location to get outdoor air quality comparisons in the Data and Insights tab. There\u2019s a How To tab with videos on setup, replacing your filters and cleaning the machine. The app can also be used for a sleep timer and scheduling times and fan settings.<\/p>\n<p>The onboard particle meter enables an auto mode that\u2019ll kick in when pollutants are detected. I found it did a pretty good job of detecting smoke when I lit incense in an adjacent room. Throughout the week or so that I left it in auto mode, my AQ monitors stayed happily in the green, but when cooking smells or some other event dropped their levels, I noticed the purifier was almost always already on the job. As for the burn test, the HushJet performed well in cleaning up both particulate and VOC levels, though the built-in PM meter seemed to exaggerate the pollutant levels, indicating far higher numbers than either of my control monitors.<\/p>\n<p>You\u2019ll have to decide for yourself if the aesthetic is for you. Both my husband and kid said \u201cOh, from the future!\u201d when they saw it. And the shiny blue turbine nozzles do give off space traveller vibes. It comes in silver and white in addition to the black and blue of my review unit and it only stands about 19 inches high, so it\u2019s not terribly intrusive (unlike the Quidditch goal post that was the <ins>Dyson Purifier Cool<\/ins>).<\/p>\n<p>There are onboard buttons and a small built-in display, but I found it far easier to just use the (well-designed) app. It\u2019s a bit pricey at $350, and the filter costs have yet to be determined. But the HEPA filter can go up to five years (depending on usage), so that\u2019s one less thing to think about. The carbon filter, however, does need to be replaced annually.<\/p>\n<\/div>\n<div class=\"flex flex-col rounded-lg bg-marshmallow p-5 @xl\/p:flex-row dark:bg-batcave clear-right mb-5\">\n<div class=\"flex-1 border-solid border-dirty-seagull dark:border-charcoal border-b @xl\/p:border-b-0 @xl\/p:border-r-2 mb-6 mr-0 pb-6 pr-0 @xl\/p:mb-0 @xl\/p:mr-4 @xl\/p:pb-0 @xl\/p:pr-4\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Pros<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Extra silent<\/li>\n<li class=\"list-disc\">HEPA filter can last for five years<\/li>\n<li class=\"list-disc\">Easy setup<\/li>\n<li class=\"list-disc\">Good at adjusting to detected pollutants<\/li>\n<\/ul>\n<\/div>\n<div class=\"flex-1\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Cons<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">More expensive than similarly sized models<\/li>\n<li class=\"list-disc\">Modern aesthetic might not be for everyone<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>$297 at Amazon<\/p>\n<div class=\"mt-4\">\n<div class=\"mb-3 flex items-center font-semibold\">Explore More Buying Options<\/div>\n<p>$300 at Target$300 at Dyson<\/p><\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"commerce productModule [&amp;+.productModule]:mt-9 [&amp;+.productModule]:border-t [&amp;+.productModule]:border-dirty-seagull [&amp;+.productModule]:pt-2 [&amp;+:not(.productModule)]:mt-10 col-body\" id=\"0261b3913a964205b8c597753f2c156b\">\n<div class=\"mt-6 text-batcave @container\/p dark:text-grey-hair\">\n<div class=\"block\">\n<div class=\"relative mb-4 w-full overflow-hidden rounded-lg border border-grey-hair pb-[75%] @xl\/p:pb-[56.25%]\"><img decoding=\"async\" alt=\"Image for the large product module\" class=\"mx-auto my-0 size-full bg-white object-contain @xl\/p:transition-transform @xl\/p:duration-300 @xl\/p:ease-in-out @xl\/p:group-hover:scale-110 @xl\/p:motion-reduce:group-hover:transition-none\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2025\/12\/f62260a0-f61c-11ef-aff1-c613a2c7b387-1.jpg\" loading=\"lazy\" height=\"720\" width=\"1280\" title=\"f62260a0-f61c-11ef-aff1-c613a2c7b387-1\"><\/p>\n<p class=\"absolute -right-0.5 bottom-0 rounded-bl-none rounded-br-lg rounded-tl-lg rounded-tr-none bg-white\/90 px-3 py-2 text-[10px]\/3 text-battleship\">Amy Skorheim for Engadget<\/p>\n<\/div>\n<div class=\"mx-0 my-auto overflow-visible @xl\/p:grow\">\n<div class>\n<h3 class=\"mb-1 text-xl\/[1.3] font-bold @xl\/p:text-2xl\/tight\">Most attractive air purifier<\/h3>\n<h4 class=\"m-0 text-lg\/6 font-bold\">Windmill air purifier<\/h4>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"commerce-desc mb-5 mt-2 space-y-6 text-base\/relaxed md:text-lg\/8 [&amp;_li]:ml-4 [&amp;_ol&gt;li]:list-decimal [&amp;_ol]:space-y-6 [&amp;_ul&gt;li]:list-disc [&amp;_ul]:space-y-6\">\n<p><strong>Filters<\/strong>: Pre, activated carbon, HEPA | <strong>Auto Mode<\/strong>: Yes | <strong>App-connected<\/strong>: Yes | <strong>Sleep mode<\/strong>: Yes | <strong>Coverage area in 30 minutes<\/strong>: 975 sq.ft. | <strong>Max decibels<\/strong>: 74 | <strong>Weight<\/strong>: 21 lbs | <strong>Filter replacements<\/strong>: $60<\/p>\n<p>If you\u2019ve indicated any interest in air purifiers during your online travels, there\u2019s a good chance you\u2019ve seen ads for <ins>Windmill<\/ins>. Like Molekule machines from a couple of years ago, these things are (digitally) everywhere.<\/p>\n<p>A big part of the appeal is aesthetics. Windmill models come in white, navy or bamboo finishes and, instead of the usual cylindrical tower shape, these have a squat, oblong design. Air is only pulled in through one side, which happens to be the side opposite the controls, so you\u2019ll have to be careful about where you put it to ensure it gets enough airflow. It\u2019s also unusually heavy at 21 pounds. Models with similar room-size ratings are often half that weight.<\/p>\n<p>The app is pretty spare, with fan and mode controls, along with a particle meter readout, a few device settings and automations for setting schedules. The device itself has buttons and LED pips for fan and mode control and a small indicator light that changes from green to red to signal the air quality (Windmill also uses PM only to gauge the air).<\/p>\n<p>In my tests, the Windmill more efficiently cleared the VOCs from the room when it was on lower fan settings. I suppose that makes sense in a way, as slower moving air spends more time passing through the carbon layer, which should theoretically trap more chemicals \u2014 but this was the only purifier I noticed that seemed to prove that theory.<\/p>\n<p>There\u2019s also a boost mode if you need to clear a bunch of air at once. It was one of the loudest fan speeds I tested, clocking in at 74 decibels on my sound meter app, but the lowest fan speed is inaudible. I appreciated that there are two sleep modes, whisper and white noise, with the latter setting the fan speed to what sounds like between medium and high and shuts off the LED lights.<\/p>\n<p>Both Blueair and the Levoit Core models performed better overall than the Windmill \u2014 and both are cheaper \u2014 but if having an air purifier that doesn\u2019t look like it belongs in a doctor\u2019s office is important to you, this is an attractive way to go.<\/p>\n<\/div>\n<div class=\"flex flex-col rounded-lg bg-marshmallow p-5 @xl\/p:flex-row dark:bg-batcave clear-right mb-5\">\n<div class=\"flex-1 border-solid border-dirty-seagull dark:border-charcoal border-b @xl\/p:border-b-0 @xl\/p:border-r-2 mb-6 mr-0 pb-6 pr-0 @xl\/p:mb-0 @xl\/p:mr-4 @xl\/p:pb-0 @xl\/p:pr-4\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Pros<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Attractive design<\/li>\n<li class=\"list-disc\">Simple set up<\/li>\n<li class=\"list-disc\">The app is easy to use<\/li>\n<\/ul>\n<\/div>\n<div class=\"flex-1\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Cons<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">More expensive than other, higher-performing options<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>$374 at Amazon<\/p>\n<div class=\"mt-4\">\n<div class=\"mb-3 flex items-center font-semibold\">Explore More Buying Options<\/div>\n<p>$400 at Wayfair$499 at Target<\/p><\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"commerce productModule [&amp;+.productModule]:mt-9 [&amp;+.productModule]:border-t [&amp;+.productModule]:border-dirty-seagull [&amp;+.productModule]:pt-2 [&amp;+:not(.productModule)]:mt-10 col-body\" id=\"0699f561f9754cae810d16c0f9d750e8\">\n<div class=\"mt-6 text-batcave @container\/p dark:text-grey-hair\">\n<div class=\"block\">\n<div class=\"relative mb-4 w-full overflow-hidden rounded-lg border border-grey-hair pb-[75%] @xl\/p:pb-[56.25%]\"><img decoding=\"async\" alt=\"Image for the large product module\" class=\"mx-auto my-0 size-full bg-white object-contain @xl\/p:transition-transform @xl\/p:duration-300 @xl\/p:ease-in-out @xl\/p:group-hover:scale-110 @xl\/p:motion-reduce:group-hover:transition-none\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2025\/12\/f62260a1-f61c-11ef-9d44-23829188682f-1.jpg\" loading=\"lazy\" height=\"720\" width=\"1280\" title=\"f62260a1-f61c-11ef-9d44-23829188682f-1\"><\/p>\n<p class=\"absolute -right-0.5 bottom-0 rounded-bl-none rounded-br-lg rounded-tl-lg rounded-tr-none bg-white\/90 px-3 py-2 text-[10px]\/3 text-battleship\">Amy Skorheim for Engadget<\/p>\n<\/div>\n<div class=\"mx-0 my-auto overflow-visible @xl\/p:grow\">\n<div class>\n<h3 class=\"mb-1 text-xl\/[1.3] font-bold @xl\/p:text-2xl\/tight\">Honorable mention: Best kids&#8217; room air purifier<\/h3>\n<h4 class=\"m-0 text-lg\/6 font-bold\">Levoit Sprout air purifier<\/h4>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"commerce-desc mb-5 mt-2 space-y-6 text-base\/relaxed md:text-lg\/8 [&amp;_li]:ml-4 [&amp;_ol&gt;li]:list-decimal [&amp;_ol]:space-y-6 [&amp;_ul&gt;li]:list-disc [&amp;_ul]:space-y-6\">\n<p><strong>Filters<\/strong>: Pre, activated carbon, HEPA | <strong>Auto Mode<\/strong>: Yes | <strong>App-connected<\/strong>: Yes | <strong>Sleep mode<\/strong>: Yes, plus white noise\/night light | <strong>Coverage area in 30 minutes<\/strong>: 300 sq.ft. | <strong>Max decibels<\/strong>: 64 | <strong>Weight<\/strong>: 6.4 lbs | <strong>Filter replacements<\/strong>: $40<\/p>\n<p>In January of this year, Levoit added this cute, kid-focused model to its air purifier lineup \u2014 that already includes two of our top picks. The Levoit Sprout combines air purification with a nightlight and basic white noise functions in a petite package. The app gives you full control over the lights, sounds and purifier settings, but the onboard controls are equally effective \u2014 important for parents who need to quickly make bedtime adjustments without having to hunt down their phone.<\/p>\n<p>I set it up in my kids room and was pleased with the simple but perfectly adequate sleep functions. Rain, waves, music and forest sounds can be combined with a soft amber light which you can set to turn off after a few minutes or up to an hour. And all the functions, from fan speed to light levels and sound can be scheduled within the app as well.<\/p>\n<p>Of course, these features would be pointless if the air purification wasn\u2019t up to snuff \u2014 but in my testing, it was able to clear out the incense smoke from a bedroom as quickly as larger machines. Possibly my favorite part of the machine is the internal air quality sensor. Most purifiers with an auto setting just detect particulate matter; this one measures particulates in three different micron measurements as well as VOCs, humidity, temperature and CO2 levels. After cooking, when my AQ monitor showed VOC levels spiking, other purifiers blissfully thought all was well, but the Sprout\u2019s auto setting kicked the purifier into high gear.<\/p>\n<p>At $280, it\u2019s actually more expensive than its bigger sibling, our top pick the Levoit Core 400S, but that model lacks the extra sensors \u2014 and the charming sleep functions.<\/p>\n<\/div>\n<div class=\"flex flex-col rounded-lg bg-marshmallow p-5 @xl\/p:flex-row dark:bg-batcave clear-right mb-5\">\n<div class=\"flex-1 border-solid border-dirty-seagull dark:border-charcoal border-b @xl\/p:border-b-0 @xl\/p:border-r-2 mb-6 mr-0 pb-6 pr-0 @xl\/p:mb-0 @xl\/p:mr-4 @xl\/p:pb-0 @xl\/p:pr-4\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Pros<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Includes a nightlight and sleep sounds<\/li>\n<li class=\"list-disc\">Has a VOC, temperature, humidity, CO2 and PM sensors<\/li>\n<li class=\"list-disc\">Great cleaning performance for the price<\/li>\n<\/ul>\n<\/div>\n<div class=\"flex-1\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Cons<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Best for small rooms<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>$280 at Amazon<\/p><\/div>\n<\/div>\n<\/div>\n<div class=\"commerce productModule [&amp;+.productModule]:mt-9 [&amp;+.productModule]:border-t [&amp;+.productModule]:border-dirty-seagull [&amp;+.productModule]:pt-2 [&amp;+:not(.productModule)]:mt-10 col-body\" id=\"237ab23c1fe641c4be23e2bef68b9dc8\">\n<div class=\"mt-6 text-batcave @container\/p dark:text-grey-hair\">\n<div class=\"block\">\n<div class=\"relative mb-4 w-full overflow-hidden rounded-lg border border-grey-hair pb-[75%] @xl\/p:pb-[56.25%]\"><img decoding=\"async\" alt=\"Image for the large product module\" class=\"mx-auto my-0 size-full bg-white object-contain @xl\/p:transition-transform @xl\/p:duration-300 @xl\/p:ease-in-out @xl\/p:group-hover:scale-110 @xl\/p:motion-reduce:group-hover:transition-none\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2025\/12\/f62287b0-f61c-11ef-beef-8398fa687639.jpg\" loading=\"lazy\" height=\"720\" width=\"1280\" title=\"f62287b0-f61c-11ef-beef-8398fa687639\"><\/p>\n<p class=\"absolute -right-0.5 bottom-0 rounded-bl-none rounded-br-lg rounded-tl-lg rounded-tr-none bg-white\/90 px-3 py-2 text-[10px]\/3 text-battleship\">Amy Skorheim for Engadget<\/p>\n<\/div>\n<div class=\"mx-0 my-auto overflow-visible @xl\/p:grow\">\n<div class>\n<h3 class=\"mb-1 text-xl\/[1.3] font-bold @xl\/p:text-2xl\/tight\">Honorable mention<\/h3>\n<h4 class=\"m-0 text-lg\/6 font-bold\">Blueair Blue Pure 311i Max<\/h4>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"commerce-desc mb-5 mt-2 space-y-6 text-base\/relaxed md:text-lg\/8 [&amp;_li]:ml-4 [&amp;_ol&gt;li]:list-decimal [&amp;_ol]:space-y-6 [&amp;_ul&gt;li]:list-disc [&amp;_ul]:space-y-6\">\n<p><strong>Filters<\/strong>: Pre, activated carbon, HEPASilent | <strong>Auto Mode<\/strong>: Yes | <strong>App-connected<\/strong>: Yes | <strong>Sleep mode<\/strong>: Yes | <strong>Coverage area in 30 minutes<\/strong>: 929 sq.ft. | <strong>Max decibels<\/strong>: 69 | <strong>Weight<\/strong>: 7.8 lbs | <strong>Filter replacements<\/strong>: $45<\/p>\n<p>Figuring out whether slick marketing terms translate to actual performance is a big part of testing gadgets. Blueair\u2019s buzzterm is HEPASilent, a process that adds an electrostatic charge to particles that enter the filter. The particles are then more apt to cling to the multi-surface structure of the filter and become trapped. Because the pollutants are stickier, the filter itself is less dense, so the fan doesn\u2019t need to work as hard to pull the air through \u2014 and the fan is the noisy part of any purifier.<\/p>\n<p>In my testing, the Blueair Blue Pure 311i Max did outperform other models when it came to reducing PM levels after an incense burn. It wasn\u2019t quite as good at lowering the VOC levels compared to other units, however, landing somewhere in the middle of the results range.<\/p>\n<p>The device itself has an attractive, minimalistic design. Instead of an all-plastic tower, the Blue Pure has a softer appearance thanks to the mesh fabric prefilter that covers the bottom three-quarters. Prefilters are an air purifier\u2019s first line of defence, catching the biggest bits like pet hair and larger dust specks, so it\u2019s nice that this one is vacuumable, removable and even washable.<\/p>\n<p>I tested the standard filter model, but Blueair also sells filters for specific pollutants: one for dust and one for allergens. The smoke-focused model has more activated carbon, which could help it remove VOCs better. But, instead of $50 a pop, those filters are $65 and $70 apiece, respectively.<\/p>\n<p>Both the onboard controls and the app are no-frills, letting you control the fan speed and turn on the sleep or auto mode. Like other air purifiers, the included sensor relies on elevated particular matter to kick in the automatic cleaning mode. In addition to scheduling, the app can also detect when you\u2019re on the way home and start up the machine before you arrive. That means giving the app location permissions that it uses at all times \u2014 not just when you\u2019re using the app \u2014 which could be a battery drain on your phone.<\/p>\n<p>The price is reasonable at $230, but the overall filtering performance of the Levoit Core 400S was slightly better, leading me to keep it in its top spot on our list. Still, there\u2019s a lot to like about Blue Pure.<\/p>\n<\/div>\n<div class=\"flex flex-col rounded-lg bg-marshmallow p-5 @xl\/p:flex-row dark:bg-batcave clear-right mb-5\">\n<div class=\"flex-1 border-solid border-dirty-seagull dark:border-charcoal border-b @xl\/p:border-b-0 @xl\/p:border-r-2 mb-6 mr-0 pb-6 pr-0 @xl\/p:mb-0 @xl\/p:mr-4 @xl\/p:pb-0 @xl\/p:pr-4\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Pros<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Good at cleaning particulate matter<\/li>\n<li class=\"list-disc\">Attractive design<\/li>\n<li class=\"list-disc\">Comparatively affordable price<\/li>\n<li class=\"list-disc\">External, washable pre-filter softens the look<\/li>\n<\/ul>\n<\/div>\n<div class=\"flex-1\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Cons<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">VOC cleaning performance not as strong<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>$200 at Amazon<\/p>\n<div class=\"mt-4\">\n<div class=\"mb-3 flex items-center font-semibold\">Explore More Buying Options<\/div>\n<p>$218 at Wayfair$229 at Chewy<\/p><\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"commerce productModule [&amp;+.productModule]:mt-9 [&amp;+.productModule]:border-t [&amp;+.productModule]:border-dirty-seagull [&amp;+.productModule]:pt-2 [&amp;+:not(.productModule)]:mt-10 col-body\" id=\"aa2f7ab0d44e40a6bf49fa7921c6aeff\">\n<div class=\"mt-6 text-batcave @container\/p dark:text-grey-hair\">\n<div class=\"block\">\n<div class=\"relative mb-4 w-full overflow-hidden rounded-lg border border-grey-hair pb-[75%] @xl\/p:pb-[56.25%]\"><img decoding=\"async\" alt=\"Image for the large product module\" class=\"mx-auto my-0 size-full bg-white object-contain @xl\/p:transition-transform @xl\/p:duration-300 @xl\/p:ease-in-out @xl\/p:group-hover:scale-110 @xl\/p:motion-reduce:group-hover:transition-none\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2025\/12\/c58ade80-1f72-11ef-beff-dba47e93f6d3.jpg\" loading=\"lazy\" height=\"720\" width=\"1280\" title=\"c58ade80-1f72-11ef-beff-dba47e93f6d3\"><\/p>\n<p class=\"absolute -right-0.5 bottom-0 rounded-bl-none rounded-br-lg rounded-tl-lg rounded-tr-none bg-white\/90 px-3 py-2 text-[10px]\/3 text-battleship\">Photo by Amy Skorheim \/ Engadget<\/p>\n<\/div>\n<div class=\"mx-0 my-auto overflow-visible @xl\/p:grow\">\n<div class>\n<h3 class=\"mb-1 text-xl\/[1.3] font-bold @xl\/p:text-2xl\/tight\">A bio-based air purifier option<\/h3>\n<h4 class=\"m-0 text-lg\/6 font-bold\">NeoPx<\/h4>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"commerce-desc mb-5 mt-2 space-y-6 text-base\/relaxed md:text-lg\/8 [&amp;_li]:ml-4 [&amp;_ol&gt;li]:list-decimal [&amp;_ol]:space-y-6 [&amp;_ul&gt;li]:list-disc [&amp;_ul]:space-y-6\">\n<p>If, like me, you\u2019re obsessed with the recent conversations surrounding the gut biome, you might find yourself wondering what <em>else<\/em> industrious bacteria can do. The team at Neoplants must have wondered the same thing, because they recently released a potted pothos houseplant, called Neo Px, that uses engineered soil bacteria to help the plant absorb and break down three harmful VOCs: benzene, toluene and xylene. The chemicals can be found in cigarette smoke, wildfires, adhesives, solvents, petroleum products and cleaning products \u2014 and their effects range from headaches and dizziness to increased cancer risk.<\/p>\n<p>I got a chance to try one out and am intrigued by both the concept and the execution. Unfortunately, the consumer-grade equipment I have on hand isn\u2019t sophisticated enough to actually test the plant\u2019s effectiveness. As Neoplant\u2019s CTO explained to me, home AQ monitors ping on a few select VOCs and extrapolate from those measurements a general sense of a room\u2019s total chemical levels.<\/p>\n<p>This is one instance in a product review when I\u2019m relying on evidence offered up by a company instead of first-hand testing. But the data in Neoplants\u2019 whitepaper is pretty comprehensive, and includes results from experiments designed and run in collaboration with the Energy Environment Research Center at IMT Nord Europe, a French graduate school of engineering. The short version of the results is that one Neo Px amounts to the same air-filtering abilities of 30 similarly sized plants.<\/p>\n<p>The plant itself is the humble (and hard-to-kill) pothos, with lots of large leaves to help in the process of air purification. The Neo Px pot is pretty clever in itself, with a reservoir-and-wick watering system that tells you when it needs more water \u2014 something I wish all my plants could do. Ventilation at the bottom of the pot exposes the soil to air, which is key to increasing the filtering action as the roots and soil have been shown to do most of the heavy cleaning.<\/p>\n<p>To increase what that soil can do, Neoplant scientists tweaked the microbial ecosystem by forcing a strain of rhizosphere (root-adjacent) bacteria to undergo thousands of forced evolutions. After exposing the bacteria to high concentrations of VOCs, they bred the survivors and repeated the procedure over the course of five years.<\/p>\n<p>The plant you\u2019re shipped (in brilliantly protective packaging) has high concentrations of the bacteria already at work. But as the plant goes about its life, eating chemicals and soaking up sunshine, the microbiome activity decreases, which is why a six-month supply of powdered bacteria ships in the box. Once per month, you mix the Power Drops (a substance that looks and faintly smells like powdered coffee creamer) with water in the little included glass beaker and add it to the soil.\u00a0<\/p>\n<p>Just recently, NeoPlants released a version of Power Drops for use with any houseplant (just not succulents) to boost the air cleaning capabilities.\u00a0<\/p>\n<p>If you go for the whole plant, it should last for years with minimal maintenance, as pothos do, but the Power Drops make up an ongoing cost associated with a Neo Px, to the tune of about $60 to $120 per year, depending on whether you subscribe for auto-refills. That\u2019s on par with the range for filter replacement costs on most standard air purifiers.<\/p>\n<p>Then there\u2019s the initial cost of either $119 or $99, depending on whether you sign up for regular deliveries of the soil bacteria. That\u2019s cheaper than a standard air purifier, but a little pricier than a houseplant, which you can find online for between $40 and $80, for around $20 at your local plant store, or practically free if you snag a cutting from a friend and an old pot.<\/p>\n<p>Of course, no matter how good a plant is at sucking up toxins, it can\u2019t deal with particulate matter, one of the two air quality issues regular purifiers address. Still, it\u2019s a great looking, abundant pothos with a long shelf life, a clever watering system and some friendly bacteria that silently suck in some of the VOCs in your air in the most energy-efficient way possible.<\/p>\n<\/div>\n<div class=\"flex flex-col rounded-lg bg-marshmallow p-5 @xl\/p:flex-row dark:bg-batcave clear-right mb-5\">\n<div class=\"flex-1 border-solid border-dirty-seagull dark:border-charcoal border-b @xl\/p:border-b-0 @xl\/p:border-r-2 mb-6 mr-0 pb-6 pr-0 @xl\/p:mb-0 @xl\/p:mr-4 @xl\/p:pb-0 @xl\/p:pr-4\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Pros<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Needs no electricity<\/li>\n<li class=\"list-disc\">Low maintenance plant with a long life span<\/li>\n<li class=\"list-disc\">Clever pot design indicates water needs<\/li>\n<li class=\"list-disc\">Neoplants experiments show its effective at removing certain VOCs<\/li>\n<\/ul>\n<\/div>\n<div class=\"flex-1\"><span class=\"space-x-2 text-lg\/6 font-bold uppercase\"><span>Cons<\/span><\/span><\/p>\n<ul class=\"mt-2 pl-6 leading-relaxed @xl\/p:text-lg\/[30px]\">\n<li class=\"list-disc\">Does not clean particulate matter<\/li>\n<li class=\"list-disc\">Somewhat expensive for a houseplant<\/li>\n<li class=\"list-disc\">Requires monthly addition of Power Drops to be most effective<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p>$119 at Neoplants<\/p><\/div>\n<\/div>\n<\/div>\n<h2 class=\"heading-mb col-body heading-text-style font-bold charcoal-color\" data-jump-link-target id=\"what-an-air-purifier-can-and-cant-do\">What an air purifier can and can\u2019t do<\/h2>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">There are three key categories of air pollution that adversely affect the quality of the air you breathe: volatile organic compounds (VOC), particulate matter (PM2.5 and PM10) and carbon dioxide. VOCs are emitted gasses that can come from cleaners, off-gassing plastics, paint, solvents, fragrances, cooking food and, ironically, air fresheners. VOCs are most closely related to odors you can smell. High levels can irritate your breathing passages, cause headaches and may become cancer-causing over time. Air purifiers with activated charcoal components can help clean VOCs from the air.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Particulate matter is usually discussed as PM2.5 and PM10, with the numbers indicating particle size in microns. This is dust, dirt, mold, smoke and, again, emissions from cooking food. Higher levels of PM can lead to respiratory irritation, allergy symptoms, respiratory infections and potentially lung cancer. Air purifiers that include a HEPA or particle filter can help remove airborne particles from your space.<\/p>\n<div class=\"col-fullbleed mb-4 bg-marshmallow pb-5 dark:bg-ramones md:invisible md:mb-0 md:h-0 md:overflow-hidden md:pb-0\">\n<div class=\"py-2 text-center text-xs uppercase\">Advertisement<\/div>\n<div class=\"flex w-full flex-nowrap justify-center\">\n<div class=\"flex\" id=\"_R_14bipqtialuknpfmlbH1_\">\n<div class=\"flex size-full items-center justify-center bg-marshmallow text-center leading-3\">Advertisement<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Carbon dioxide is what humans and pets breathe out. Elevated levels can cause dizziness and lethargy. But no air purifier can reduce CO2 levels because the molecules are so small. Plants can help to some extent, but really the only solution is opening a window or otherwise ventilating the space.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">There are no federal standards for air purifiers, but the state of California does require all air cleaners sold in the state to be certified by the California Air Resources Board (CARB). All of our top picks here have met that certification.<\/p>\n<h2 class=\"heading-mb col-body heading-text-style font-bold charcoal-color\" data-jump-link-target id=\"what-to-look-for-in-an-air-purifier\">What to look for in an air purifier<\/h2>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"hepa-filters-and-other-filter-types\"><strong>HEPA filters and other filter types<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">An air purifier isn\u2019t an overly complicated device. Smart modes and app connectivity aside, they\u2019re not much more than a filter and a fan, which you can certainly DIY. The fan pulls air through the filter to capture particulate matter and other unhealthy elements so you don\u2019t breathe them in. The type of fan can make some difference \u2014 it should be powerful enough to pull in air quickly, but also quiet enough on its low speed so it can unobtrusively clean all day long.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Filters, on the other hand, are more varied. Most have two or more layers, typically a pre-filter, an activated carbon filter and sometimes a particle or even a true HEPA filter. The pre-filter is made from a fine mesh that captures big stuff like pet hair and larger chunks of dust. Sometimes this part is separate from the more technical filters \u2014 which means you can remove and clean it without needing to swap out the whole thing. For all-in-one filters, you can vacuum the outside of it to remove larger particles.<\/p>\n<div class=\"col-fullbleed mb-4 bg-marshmallow pb-5 dark:bg-ramones md:invisible md:mb-0 md:h-0 md:overflow-hidden md:pb-0\">\n<div class=\"py-2 text-center text-xs uppercase\">Advertisement<\/div>\n<div class=\"flex w-full flex-nowrap justify-center\">\n<div class=\"flex\" id=\"_R_163ipqtialuknpfmlbH1_\">\n<div class=\"flex size-full items-center justify-center bg-marshmallow text-center leading-3\">Advertisement<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">An activated carbon or activated charcoal layer is extremely porous, tightly packed coal that presents a vast amount of microscopic surface area to the passing air. Gaseous chemicals, VOCs and other molecules become lodged in the crannys and stick. This is the layer that gets rid of odors.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Nearly all types of air purifiers include a particle filter. Some of those can be called &#8220;true HEPA&#8221; (high-efficiency particulate air) filters \u2014 meaning they conform to the standards set out by the DOE. Particle filters are made up of pleated masses of ultrafine fibers that force air to take a convoluted path in order to pass through. This traps and absorbs tiny molecules of smoke and dust, allergens like dander and pollen, and some viruses and bacteria.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Since all of these air filters physically trap particulates, they\u2019ll eventually fill up and become less effective. Most manufacturers recommend replacing the filter every six months, while others claim a year-long life span. Most smart air purifiers will let you know in the app when it\u2019s time to replace. When you\u2019re considering a unit\u2019s cost, be sure to factor in the expense of replacement filters, which you may end up buying twice a year.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"room-size\"><strong>Room size<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Air purifiers list their air filtration capabilities in terms of room size and frequency of air exchanges, sometimes listed as clean air delivery rate (CADR) or you may see a number for cubic feet per minute (CFM). A smaller unit might say it can exchange the air in a 500-square-foot room twice per hour. So that model should be able to pass all of the air in a 250-square-foot room through the filter every 15 minutes, but a 1,000-square-foot room would probably be outside its effective range. Of course, there\u2019s no standard for manufacturers to adhere to when it comes to these calculations, but typically, larger air purifiers can handle large rooms.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\"><strong>Controls<\/strong><\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">In our testing, we focused on Wi-Fi-connected \u201csmart\u201d air purifiers with companion apps that can monitor air quality and adjust the fan settings as needed. Within the apps, you can control auto-clean settings, set timers and schedules and check the health of the filter as well. Most will remind you when it\u2019s time to get a replacement, and let you order one directly from the manufacturer through the app. You can also see the current and historical readings from the internal air quality (AQ) sensor. Most determine air quality through an optical particle meter, though some brands like Dyson and Molekule also include chemical sensors for VOC measurements. When levels of particulates become elevated, the fans switch up to high speed to move more air through until the quality improves.<\/p>\n<div class=\"col-fullbleed mb-4 bg-marshmallow pb-5 dark:bg-ramones md:invisible md:mb-0 md:h-0 md:overflow-hidden md:pb-0\">\n<div class=\"py-2 text-center text-xs uppercase\">Advertisement<\/div>\n<div class=\"flex w-full flex-nowrap justify-center\">\n<div class=\"flex\" id=\"_R_183ipqtialuknpfmlbH1_\">\n<div class=\"flex size-full items-center justify-center bg-marshmallow text-center leading-3\">Advertisement<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Most smart purifiers also work with voice assistants, so if asking Alexa to turn on your air purifier makes your life easier in some way, you can do so. If you don\u2019t want to talk to an AI or grab your phone to control your purifier, getting a unit with simple on-board controls is a good idea. These can be as basic as buttons with indicator lights or as elaborate as a touchscreen panel. At minimum, it\u2019s good to have a way to control the fan speed and turn on or off auto mode on the device itself.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"design\"><strong>Design<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">As we mentioned, sticking the device as close to the middle of the room is helpful for getting the best performance. That means you\u2019ll be looking at it a lot, so design considerations matter. Most purifiers are cylindrical towers with fan vents up top. Units meant for larger rooms are not small, weighing between 12 and 20 pounds and reaching two feet tall (or in the case of the Dyson Purifier Cool, three and a half feet). Some, like Coway\u2019s Airmega IconS, take on more furniture-like designs to blend in. Others, like Dyson&#8217;s, are conspicuously designed to stand out.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"how-to-set-up-an-air-purifier\">How to set up an air purifier<\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Even the best air purifier can\u2019t do much without airflow. So ideally, you won\u2019t shove your air purifier off in a corner right next to a wall. Most manufacturers recommend at least a foot of clearance between the machine and anything that could block circulation \u2014 walls, couches, cabinets and the like. Most cylindrical models have intake vents all around the outside, but box models may have them on just one side, so make sure you point the vents outwards towards the center of the room. Smaller air purifiers work better if they\u2019re up off the ground by a couple feet, such as on top of a stool or end table. And of course, make sure the cord isn\u2019t stretching across trafficked areas to avoid tripping.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Before you plug your air purifier in, make sure to check that the filter isn\u2019t wrapped in plastic inside the machine. I probably don\u2019t need to tell you how I know this is a very important first step. The purifiers we recommend are smart home models, so the next step will usually involve downloading the manufacturer\u2019s app to your phone and connecting the air purifier to the app as well as your home\u2019s Wi-Fi.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"additional-steps-for-clearing-the-air\">Additional steps for clearing the air<\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Air purifiers, as the name suggests, clean the air. Once dust, dander and smoke settle onto surfaces, there isn\u2019t much these machines can do to eradicate them. So vacuuming and good old-fashioned dusting are important steps to keep allergens and particulate matter at bay. If you have an HVAC system, changing or even upgrading your system\u2019s air filters can help keep bad air in check. The American Lung Association recommends filters with at least a MERV-13 rating. The association also recommends not burning candles in your home, foregoing air fresheners and opting for homemade cleaning supplies over chemical cleaners.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"when-an-air-purifier-just-isnt-enough\"><strong>When an air purifier just isn\u2019t enough<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">The most striking bit of knowledge I picked up from testing air purifiers is how effective opening windows can be on indoor air quality. What took an air purifier a half hour to clear out took mere minutes when I opened my front door and a few windows. Every variable measured by the air quality sensors, including VOCs, PM, and particularly CO2 levels (which air purifiers can\u2019t alleviate), improved dramatically after exposure to fresh air \u2014 significantly faster and better than any machine we tested.<\/p>\n<div class=\"col-fullbleed mb-4 bg-marshmallow pb-5 dark:bg-ramones md:invisible md:mb-0 md:h-0 md:overflow-hidden md:pb-0\">\n<div class=\"py-2 text-center text-xs uppercase\">Advertisement<\/div>\n<div class=\"flex w-full flex-nowrap justify-center\">\n<div class=\"flex\" id=\"_R_1aripqtialuknpfmlbH1_\">\n<div class=\"flex size-full items-center justify-center bg-marshmallow text-center leading-3\">Advertisement<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Letting in fresh air for just fifteen minutes each day can help, according to the Lung Association. On very cold days, do it midday. When it\u2019s hot, open windows in the early morning when it\u2019s coolest. When I did it in the middle of winter, my HVAC system had to work a little overtime afterwards, but venting a room was the most surefire way of getting air quality quickly back in the green.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Of course, if the air outside is unhealthy from wildfire smoke or run-of-the-mill pollution, or if you&#8217;re dealing with seasonal allergies, throwing open the windows won\u2019t work and an air purifier might be the best way to consistently clean things up.<\/p>\n<h2 class=\"heading-mb col-body heading-text-style font-bold charcoal-color\" data-jump-link-target id=\"how-we-test-air-purifiers\">How we test air purifiers<\/h2>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">My living room is not a science lab; there\u2019s far too much pet hair for that to be the case. Still, I went beyond just turning stuff on and sniffing the air by acquiring two consumer-grade indoor air quality monitors that performed well in laboratory assessments, the Element from Awair and the uHoo Smart Air Monitor. I conducted burn tests in this medium-sized room by measuring the ambient air quality, then burned a brick of pi\u00f1on incense for twenty minutes and measured the air again. Then I ran one purifier at its highest speed for thirty minutes and recorded levels, then ran the unit on the lowest setting for a half hour and remeasured. I made note of the sound levels using a simple iPhone app to compare one machine\u2019s noise level to the next.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Over the course of a month, I used each unit in different scenarios (such as in the basements where the cat litter box is) and tried out each device\u2019s smart features, controls and auto modes. I also just lived with them and evaluated how they fit into everyday life. As new purifiers come on the market we continue to acquire units that seem worthy of inclusion. Most recently, we tested purifiers from Blueair, IQAir, Windmill and others, adding our findings to this guide.<\/p>\n<h2 class=\"heading-mb col-body heading-text-style font-bold charcoal-color\" data-jump-link-target id=\"other-air-purifiers-we-tested\"><strong>Other air purifiers we tested<\/strong><\/h2>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"blueair-mini-restful\">Blueair Mini Restful<\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">I appreciate a good multi-tasker. The Blueair Mini Restful combines a small-room air purifier with a sunrise alarm clock and night light. It reminds me of a grown up version of Levoit\u2019s Sprout purifier, which is geared towards kids with its white noise and night light functions. The Mini Restful is definitely small enough to pop on a night stand so it would be pretty handy if it could replace your alarm clock up there.<\/p>\n<div class=\"col-fullbleed mb-4 bg-marshmallow pb-5 dark:bg-ramones md:invisible md:mb-0 md:h-0 md:overflow-hidden md:pb-0\">\n<div class=\"py-2 text-center text-xs uppercase\">Advertisement<\/div>\n<div class=\"flex w-full flex-nowrap justify-center\">\n<div class=\"flex\" id=\"_R_1d3ipqtialuknpfmlbH1_\">\n<div class=\"flex size-full items-center justify-center bg-marshmallow text-center leading-3\">Advertisement<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Unfortunately, those secondary functions feel a little incomplete. There\u2019s no timer function for the night light, only manual control. The clock readout is on the top, making it impossible to view from bed if it&#8217;s on your nightstand. The sunrise alarm clock will start lighting up at either 15 minutes or a half hour before the sound kicks in, but if the light happens to be enough to wake you, there\u2019s no way to stop the alarm from sounding without getting out your phone.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">It performed well enough in its primary function, and got a smoky bedroom back to breathable in around a half an hour of running on high. (There\u2019s no built-in sensor, so you have to manually adjust the fan through the app or onboard controls.) It\u2019s also quiet enough to run all night on low \u2014 I\u2019m fairly sensitive to noise and was able to sleep.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"iqair-healthpro-plus-se\">IQAir HealthPro Plus SE<\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">The IQAir HealthPro Plus SE is a formidable piece of equipment. The boxy tower looks like something you\u2019d see in a hospital and weighs 35 pounds, making me appreciate the included wheels when I needed to move it around. It\u2019s designed and made in Sweden and each unit comes with an impressive certificate of performance. I\u2019m certain the testing processes IQAir employs are more scientific than my tests \u2014 after all, the company is probably best known for its air quality monitors \u2014 but I found the filtration efficiency to be on par with and, in one test, worse than that of other models I tested.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">I was also disappointed that a $1,000-plus air purifier from an air monitor device company was only capable of measuring particulate matter \u2014 and not VOCs \u2014 to trigger the auto-clean function. That said, setup was simple and the app can integrate data from public air quality sources as well as other AQ monitors you may have set up.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"coways-airmega-icon-s\">Coway\u2019s Airmega Icon S<\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Coway\u2019s Airmega Icon S was our previous pick for best design. It looks more like a tiny mid-century-modern credenza than an air purifier and the little shelf up top doubles as a wireless phone charger. The PM2.5 sensor reliably kicked in the auto mode as I used it and the three-speed fan is quiet, even on high, yet powerful. I had a little trouble getting the app to connect, but the onboard touch controls worked better anyway. It\u2019s expensive at $699, too, but it does have a washable pre-filter.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"sensibo-pure\"><strong>Sensibo Pure<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">At $229, and nearly always on sale for $130, I had the Sensibo Pure pegged as a contender for a budget pick. Unfortunately, replacement filters are $99 unless you subscribe to automatic shipments and many of the app features are behind a paywall as well. It\u2019s not certified by CARB and underperformed many of the other units in the burn test, though it did return the air back to a \u201cgood\u201d rating according to the air monitors after 30 minutes. The design is inoffensive, it\u2019s not overly loud and it does integrate with Sensibo\u2019s smart AC devices, so if you\u2019re already happy with one of those, this may be a decent option.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"dyson-purifier-cool\"><strong>Dyson Purifier Cool<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Like all Dyson products, this air purifier is dripping with design. It looks like no other unit on the market and it\u2019s up to you to decide whether you like that or not. I was indifferent to the looks, but appreciated the slick and informative app, which not only displays indoor air quality, it also shows what conditions are like outside, using a clever house graphic to differentiate the two sets of numbers. I also like that it detects VOCs as well as particulates and the auto mode seemed to read the room accurately. The air coming out of the fan did indeed feel cool, though at first had a strong plastic odor. Unfortunately, it was the lowest performing unit during two separate burn tests and had repeated connectivity issues.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"molekule-air-pro\"><strong>Molekule Air Pro<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">The Molekule Air Pro comes from a brand that pays keen attention to aesthetics. It and the app have that Instagrammable, muted-modern look that countless clothing and bedsheet brands emulate these days. That style doesn\u2019t come cheap as the Air Pro costs over $1,000 and requires $140 filters. The company came under fire for and had to stop making many of its claims about its filtration system, which may have led to it filing for bankruptcy in 2023. Molekule is still able to tout its patented photoelectrochemical oxidation, which the company says destroys pollutants at a \u201cmolecular level.\u201d In my tests, it performed almost as well as the others in improving VOC and PM2.5 levels. But it\u2019s also very loud: When auto mode kicked the fan into high gear, it would make me tense. Also, I found the unit often indicated \u201cbad\u201d or \u201cvery bad\u201d levels when my two monitors indicated the air quality was actually pretty good.<\/p>\n<h2 class=\"heading-mb col-body heading-text-style font-bold charcoal-color\" data-jump-link-target id=\"air-purifier-faqs\">Air purifier FAQs<\/h2>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"what-settings-should-you-run-an-air-purifier-on\"><strong>What settings should you run an air purifier on?<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">There aren\u2019t many settings to adjust on an air purifier. Most have low, medium and high fan speeds and possibly an auto-mode that detects impurities in the air and increases the fan speed on your behalf. Air circulates through a purifier faster at higher fan-speed settings so it cleans the air more efficiently. Higher speeds also make the air purifier louder. That means you typically want to find the balance between cleaning power and noise levels.<\/p>\n<div class=\"col-fullbleed mb-4 bg-marshmallow pb-5 dark:bg-ramones md:invisible md:mb-0 md:h-0 md:overflow-hidden md:pb-0\">\n<div class=\"py-2 text-center text-xs uppercase\">Advertisement<\/div>\n<div class=\"flex w-full flex-nowrap justify-center\">\n<div class=\"flex\" id=\"_R_1hbipqtialuknpfmlbH1_\">\n<div class=\"flex size-full items-center justify-center bg-marshmallow text-center leading-3\">Advertisement<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">Other settings like timers and dimming the LED lights make the unit more comfortable to live with, particularly if you use yours in your bedroom. For everyday cleaning of the air, you\u2019re probably best off leaving the air purifier running on low, only kicking it up to high at certain times when the air is murkier, like after you cook.<\/p>\n<h3 class=\"heading-mb col-body text-[1.125rem]\/[1.375rem] font-bold charcoal-color\" data-jump-link-target id=\"what-is-a-hepa-filter\"><strong>What is a HEPA filter?<\/strong><\/h3>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\">A HEPA filter is a type of particle filter. Every air purifier has a particle filter, but not all are considered \u201ctrue HEPA\u201d filters. The specifications are determined by the US Department of Energy and require a minimum efficiency of 99.97 percent when filtering airborne particles of 0.3 microns. HEPA filters can remove dust, pollen, mold and bacteria.<\/p>\n<p class=\"col-body mb-4 leading-7 text-[18px] md:leading-8 break-words min-w-0 charcoal-color\"><em>Check out more from our <\/em><em>spring cleaning<\/em><em> guide.<\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<aside class=\"hidden flex-none md:block ml-8\">\n<div class=\"flex size-full flex-col flex-nowrap\">\n<div class=\"flex-auto\">\n<div class=\"sticky flex flex-none top-[75px] top-[95px]\" id=\"_R_74pqtialuknpfmlbH1_\">\n<div class=\"flex size-full items-center justify-center bg-marshmallow text-center leading-3\">Advertisement<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/aside>\n<\/div>\n<\/div>\n<div class=\"mx-auto md:px-10 md:max-w-[1220px]\">\n<div class=\"grid grid-cols-article-mobile md:max-w-[750px] md:grid-cols-article\">\n<div class=\"no-scrollbar col-body mx-4 mb-8 mt-2.5 overflow-x-scroll whitespace-nowrap md:mx-0 md:max-w-[750px] md:overflow-x-visible\">\n<div class=\"mx-auto max-w-screen-sm\">\n<ul class=\"inline-flex text-xs md:text-sm\">\n<li class=\"mr-6\">About our ads<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n<p> Source URL: https:\/\/www.engadget.com\/home\/smart-home\/best-air-purifier-120040002.html<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Home Smart home Why you can trust us Engadget has been testing and reviewing consumer tech since 2004.
