Another Winix, the AM90, uses the same HEPA filter as the 5500-2 and delivered virtually identical performance in our testing. Of them, the TP04 performed better, but neither measured up well against our top pick, the Coway AP-1512HH Mighty, and our large-space pick, the Blueair Blue Pure 211+. Compare; Find My Store.

Some units may still be available as dead stock, but the world needn’t lament the fallen. John Holecek, who co-wrote and performed testing for previous versions of this guide, holds a master’s degree in earth science, with a focus on climate, aerosols, and analytical chemistry. That’s wrong. After all, you won’t be sitting or sleeping with your face against your purifier. The categories also broadly correspond to price—the larger the space, generally the more expensive the purifier you need to keep the air clean. However, as you can see in this review of a malfunctioning unit, Coway responds in the thread. In a 350-square-foot room, it can deliver 5.3 air changes per hour (ACH) based on its CADR measurements, identical to the Coway AP-1512HH and slightly more than the Winix models. In 2017, we also tested the Dyson Pure Hot+Cool Link HP02 for particulate performance in the lab and in our real-world New York apartment. It did reasonably well in our testing, removing 95.2% of the smoke on high and 89.7% on medium. The Oransi OV200 has budget specs, draws as much as 60 watts (our budget pick draws 3.6 on medium) and costs much more than our budget pick. That’s about three times the five-year running cost of our top pick, the Coway Mighty. But on their highest setting, most purifiers are too loud—above 50 decibels—to be tolerable as a background for conversation, sleep, or TV watching. Take that off. The Core 300 replaces our former budget pick, the Blueair Blue Pure 411, which was considerably outperformed by the Levoit. When retesting our existing air-purifier picks, Tim took four measurements, two using the old filters and two using new filters. (See our blog post about purifiers and wildfire smoke for more.) On medium, it removed an impressive 97.3%. The prefilter catches larger particles, such as pet hair, and keeping it clean helps the HEPA filter work unimpeded on fine particles. Although the Winix FresHome P150 is similar in physical size to the Coway AP-1512HH Mighty, it has specs well below those of a small-space purifier. The huge and exceptionally powerful Medify MA-112 has the highest CADR rating we’ve ever seen: 950. The Best Air Purifiers Blueair Blue Pure 211+ From: CR’s take: The Blue Pure 211+ is one of only two models that scores Excellent for particle removal at both the high- and low-speed settings. And on Dark plus Auto, with its primary PECO purification system shut off and its fan on the equivalent of a medium setting, it reduced them by 21.3% (ambient) and 18.0% (clean). On the high setting in our 2019 New York City real-world test, the Coway Mighty reduced 0.3-micron particulate levels by 98.9% in 30 minutes, on both new filters and those that the machine had run on continuously for a year. Both of those numbers fall well below our 50-decibel limit for “quiet,” but the difference is readily audible, especially when you’re going to sleep or watching TV. Among our picks, there is one exception to this general rule: the Blue Pure 211+, our pick for large spaces. Wirecutter is reader-supported. That’s because K&N make a seriously mean Engine Air Filter that comes custom made for the unrestrict airflow for your specific make and model of vehicle. In raw performance, it stands among the best purifiers we’ve ever tested, achieving as much as 99.1% removal of airborne particulates in just 30 minutes in our latest test—and that was on year-old filters. The Blue Pure 211+ aced our tests, and its ability to move extremely high volumes of air make it our pick for large spaces. In addition to its HEPA filter, it contains a large VOC filter composed of 2.2 pounds of activated carbon and alumina. The Levoit LV-PUR131 has budget specs but costs twice as much as our budget pick. Based on its specs, it’s appropriate for rooms of just 287 square feet (where its CADR numbers result in our recommended 4 air changes per hour). Matches produce millions of very fine particulates, including those in the 0.3-micron range—the hardest size of particle to remove with mechanical filtration like HEPA. Finally, Mila offers half a dozen different filters, from plain particulate filters to those with additional VOC filters containing as much as 2 pounds of activated carbon—far more than most purifiers have. BestAIR Pro is the brand that trade professionals use and trust. That 0.3-micron diameter is not arbitrary: It is considered by the Association of Home Appliance Manufacturers, a trade group, the toughest size of particle to remove by physical, HEPA-type filtration. This put the particle counter well outside the airflow from the purifiers, eliminating the possibility of an artificially high measure of their performance and ensuring that the readings gave an accurate impression of the purifiers’ whole-room purification. HEPA air purifiers do one thing and do it very well: remove fine particles from the air. (You can’t physically block the glow with a coin or tape, because doing so would block the Molekule’s delivery of air.). We recommend avoiding this feature for two reasons. He did not attempt to hermetically seal the room—after all, we wanted to see how the machines performed in real-world conditions—but he did take steps to make it more like a room in a typical home, sealing off the office’s powerful, filtered commercial HVAC ventilation with tape and foil to minimize its impact on air movement. The Winix 5500-2 is an exceptional performer; its stark look, lack of a display shutoff, and slightly higher electrical use are (minor) shortcomings. This FRAM auto air filter couldn’t miss from the best auto air filter review list as it an excellent option for cars that are always on the road. If you have specific concerns about VOCs, the HM400 is by far the best portable air purifier we’ve ever found. In 2018, Tim conducted testing in his New York apartment similar to what he did in 2019 in Wirecutter’s New York headquarters. With a MERV rating of 16, you’ll get hospital grade filtration. The Philips 1000 Series purifiers cost more and have similar or weaker specs compared with our Coway top pick. Air pollution from US combustion emissions alone results in 200,000 premature deaths a year, according to a 2013 MIT study. Air purifiers of the kind we recommend use physical filters to trap small particles in your home’s air. Read honest and unbiased product reviews from our users. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. And it has other features we like, including very quiet performance, terrific energy efficiency, and a control panel that automatically dims after you adjust the settings. The HEPA filters should have an arrow or other marking indicating the correct orientation. Find helpful customer reviews and review ratings for BestAir ES12-2 Extended Life Humidifier Replacement Paper Wick Humidifier Filter, For Emerson, Quiet Comfort & Kenmore Models, 10" x 9.4" x 6.5", Single Pack (4 Filters) at But in our tests it performed significantly worse, achieving just 77.4% and 55.1% reduction on its highest and medium (speed 6) settings, respectively. It’s an attractive machine, too, with its simple cylindrical form and tweedlike fabric covering (which also acts as a prefilter and can be laundered to keep the prefilter performing at its best). To change the filter, you unscrew the fan component from the air filter and then pull the washable, fabric prefilter sock off the filter. We attribute the Mini’s superiority to the Molekule Air to its much bigger physical prefilter: It’s about five times larger by area than the Air’s. The Mini typically costs $400, versus $100 for the Levoit. This means HEPA purifiers would efficiently capture viruses (and any aerosolized droplets of saliva and mucus that contain them) that are drawn into their filters. We’ll be long-term testing the Winix 5500-2 over the coming months and will report on its continuing performance. We believe that the Airmega 200M, with its nearly identical design, interchangeable filters, and slightly more powerful motor, would undoubtedly perform at least as well. Finden Sie hilfreiche Kundenrezensionen und Rezensionsbewertungen für bestair Pro Plissee Ofen Filter auf He also tested a popular hack: taping a furnace filter to a box fan to create a DIY air purifier. Renpho, Aviano, Mooka, Keenstone; This model’s HEPA filter removes particulates (like pollen and smoke) from the air, and its second filter efficiently removes odors and VOC gases—an ability many purifiers lack. Another is filter-replacement costs. If you can’t find the 5500-2, consider the 5300-2, a nearly in-kind substitute. Purifiers work best in a contiguous space; if you want to clean the air in both the living room and a bedroom, for example, it’s best to get a purifier for each room or to move a single purifier around with you. In our 2020 test, it reduced a heavy load of smoke in our 135-square-foot test space by 97.4% in half an hour on high and 92.6% on medium. It’s physically quite a bit larger than the Mighty, both in height and footprint, and in a bedroom, playroom, or living room it can be a visually imposing presence. In its advice on cleaning and disinfecting homes during the pandemic, the CDC recognizes as much: “When used properly, air purifiers can help reduce airborne contaminants, including viruses, in a home or confined space.” And in its guidance for health-care personnel, the CDC states that air from rooms where COVID-19 patients are being isolated “should be exhausted directly to the outside or be filtered through a high-efficiency particulate air (HEPA) filter directly before recirculation,” and advises health-care workers to “consider the addition of portable solutions (e.g., portable HEPA filtration units) to augment air quality in areas when permanent air-handling systems are not a feasible option.”. Reviewed in the United States on March 10, 2017, Reviewed in the United States on December 25, 2016, Reviewed in the United States on January 26, 2018, Reviewed in the United States on November 24, 2019. Like many air purifiers, the Coway Mighty has an ionizing function in addition to its HEPA filtration. And the Winix is physically larger than the Coway, only comes in black, and to us is not as good-looking. But even if you decide to use an air purifier as a protective measure, we recommend that you also continue to closely follow the CDC’s other longstanding advice, including social distancing, wearing a face covering outdoors, washing your hands frequently, and treating frequently touched surfaces with disinfectants. Updated October 2020 . The Coway and Blueair scored 87.6% and 99.2%, respectively. But unlike the HEPA purifiers, all of which proved capable of deeply cleaning the air, the Molekule left the air heavily loaded with particulates on every setting. (We use smoke to test them, in fact, so our picks directly reflect their ability to remove it.) In comparison, the similarly specced GermGuardian AC5900WCA, a 2019 competitor, consumes about $60 of electricity annually and needs a new $70 filter at least every eight months—so its five-year cost is about $900. One purifier per room is best. Most of our picks have token adsorbent filters, amounting to a few ounces; in contrast, the HM400 has 15 pounds of adsorbent. That’s not just a financial concern: Since air purifiers perform best when cleaning a single room, it’s worth considering separate machines for, say, the bedroom and the living room. It’s a great value, at an up-front price often lower than $200 (and about $470 over five years, factoring in electricity and replacement filters). The Coway, on year-old filters, removed 99.6% and 89.2%, respectively—in line with all our past test results, on new or old filters. A year later, those same filters—now far past their recommended 6-month replacement schedule—those numbers barely dropped: 99.1% and 98.0%. The Winix AM90 is essentially a Winix 5500-2 in a more modern shell. Hence our emphasis on air changes per hour. We tested two purifiers from Medify, the MA-40 and the MA-112. In addition to those models, we have reviewed more than 100 purifiers since 2013, testing many of them, including the following: In our 2014 test, the Rabbit Air MinusA2 SPA-700A earned middle-of-the-road marks in performance, cost of ownership, and noise. First, we tested the Molekule exactly as we tested the HEPA purifiers: Using the ambient air conditions in the room, plus whatever particulates the burned matches added at the outset, we ran it on the four settings and recorded the particulate reduction after a half hour. We tested two tower-style units in 2017, the Coway AP-1216L and the since-discontinued LG PuriCare AS401WWA1. It has a more contemporary design that many will find more attractive (if you prefer white—the only color option). The Coway Airmega 200M is virtually identical to our top pick, the Coway AP-1512HH Mighty. Still, that works out to a manageable $7.50 a month, and the Core 300’s low up-front cost is easier to swallow than the Coway’s typical $200-plus. They are especially good at rapidly filtering out the most common airborne allergens, including dust and pollen; mold, mildew, and fungal spores; pet dander; dust mites and their excrement; soot from automobiles; and tobacco, marijuana, and wildfire smoke. Based on our seven years of testing, we know that 4 ACH ensures rapid and nearly complete cleaning of highly polluted air—a big concern during, say, a wildfire—and that anything below 4 ACH typically results in measurably worse performance. It’s a fanlike white noise, so not unpleasant, but if you are particularly noise-sensitive it’s something to bear in mind. We achieved this by running the powerful Medify MA-112 purifier on high for 15 minutes before each test, reducing the particles per cubic foot from millions to less than 10,000. It did okay, cutting the initial particulate load by 87% over 30 minutes on medium. Both results indicate that it’s a highly efficient purifier, in the same league as the Coway AP-1512HH and the Winix models above. Read more in How we picked. But this model is physically huge, at 28 inches high and 15 wide, and it’s a rare home that has an open space big enough to demand such a powerful purifier (Medify says casinos use it to clear cigarette smoke). These findings all mean that the Molekule is not remotely worth its high price: usually $800 up front, versus a typical $200 to $225 for the Coway AP-1512HH Mighty, a much more capable machine on particulates. With a CADR of 350 cubic feet per minute on high for smoke, pollen, and dust, it handily outdraws most purifiers in its price range and many machines that cost far more. The GermGuardian CDAP4500 is a small-space unit that usually costs $150—more than our pick in that category, the Levoit Core 300—mostly because it offers Wi-Fi connectivity, which isn’t useful or necessary. The medium and low settings should be quiet enough to sleep near for most people. When he’s not here, he’s on his bike. Cisno, Airthereal, iTvanila, Secura. It’s easy to forget the occasional obligation of replacing your purifier’s filters—set a calendar reminder. Model #ALL 1. The prefilter is made of sturdy, fine plastic mesh, and you can vacuum or wipe it clean, or rinse it off under a faucet; do that every month or so to keep the machine performing optimally. And the filters need to be replaced every eight months, at about $25 a pop. (You can turn the night-light and the display lights off if they disrupt your sleep.) Our review will show you some of the best cabin filters on the market that are decent replacements for your clogged-up cabin filter. Manufacturers also calculate their ratings in different ways, often resulting in inflated square-footage claims. Within 30 minutes, the Coway AP-1512HH Mighty reduced heavy smoke pollution in a 135-square-foot, 1,215-cubic-foot New York office by as much as 99.6%. So over the course of five years, its running costs may be as much as $480—far more than the Coway’s roughly $270. It also agreed to withdraw its longstanding tagline, “Finally, an air purifier that actually works.”. In the summer of 2019, we purchased a Molekule Air (the flagship model) and tested it. This model is far more expensive to run, as well, requiring a $70 replacement filter every eight months (versus $50 once a year for the Mighty) and using about $64 versus $14 of electricity annually if run 24/7 on medium, due to its much higher energy consumption. The Aair reduced particulates by 98.1% and 94.1% on high and medium in our 30-minute tests; the 211+ achieved 99.3% and 98.4% reductions in identical conditions. We have long recommended running air purifiers on high for an hour and thereafter running them on the quiet/medium setting to create and maintain clean air in the home. In addition to these performance assessments, Tim measured the purifiers’ noise output at a distance of 6 feet, 3 feet from the ground, to determine their highest so-called quiet setting (maximum 50 decibels, measured as dBA). The Coway lets you shut off the display manually, on any fan speed, but the Winix only does so automatically, and, more important, only on a single setting, sleep mode, when the fan is running its slowest. Previously, we dismissed the Airmega 200M because it was significantly more expensive, but the prices of this model and the Mighty have evened up recently. Throughout its promotional literature, Molekule used to claim its PECO technology “completely destroys” particulates in the air and contrasted this to HEPA purifiers, which, the company said, can’t capture viruses or anything else smaller than 0.3 micron (in fact, they can and do); release mold and bacteria back into the air (they don’t); and can’t capture VOCs (true of HEPA filters—but their secondary VOC filters can). And the company uses 2 air changes per hour to calculate its square-footage ratings, whereas we set 4 ACH as a minimum. The air humidifier you brought last season has helped your family members a lot, right? Both models also draw far more power than their supposed equivalents among our picks, and both cost the same or more up front. Why trust BestReviews? (Compare that with the Blue Pure 411’s measurements: 87.2% on high and 70.7% on medium.) The solution is to make the filter dense enough that it has a sufficient amount of fibers to capture most of the 0.3-micron particles. Finally, it is compact, standing just 18 inches tall, 10 inches deep, and 17 inches wide, about the size and shape of a large beach tote. While we were researching and writing this guide, LG discontinued its Air Purifier Tower AS401WWA1 and PuriCare Air Purifier Round Console. At the start of each test, he measured the ambient air quality for three minutes to get a baseline; after that, he burned five wooden matches and let the smoke circulate for two minutes to artificially raise the particulate levels in the air, and then he ran the machines for the remaining 30 minutes. You should do the same if you try this hack. Set on high, the Mighty reduced the particulate concentration by 99.9% in the first hour. The Coway has a clear edge in a few other cases, however. On its highest setting (speed 5), the Mini did well, reducing the smoke from five wooden matches by 96.2% in half an hour. Best Air Humidifier Filters (Review) 2021 – Top Picks & Buying Guide. But if you have an air-quality emergency on your hands—like regional wildfires, or your charred dinner under the broiler—and you have a box fan, tape, the right sort of filter, and no time to buy an air purifier, it’s worth a shot. At about $100, the Core 300 is inexpensive upfront, but it is not a very energy-efficient purifier, especially for its size. The QuietPure Home Air Purifier offers specs similar to those of our also-great pick for large rooms, the Blueair Blue Pure 211+, but it often costs more. That’s due to settling, in which particles fall to a room’s surfaces; agglomeration, in which two or more particles naturally combine to form a single particle; and ambient ventilation, which we standardized for all our tests. It’s a popular purifier, with a design that has gone largely unchanged for years, but even many of its adherents acknowledge that noise is an issue. Coway has a support center based in Austin, Texas; you can reach it at or 888-960-5747. Most air purifiers arrive with the filters installed—but also sealed in plastic wrappers. The Rabbit Air BioGS 2.0 also fails the 4 ACH limit for a standard-size room and costs more than our Coway top pick.
