We do dismiss air purifiers that rely on ozone (O3, a molecule composed of three oxygen atoms) to “purify” the air. 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). Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes, in theory. The Levoit costs a bit more than half as much for the same upkeep—and, of course, roundly outperforms the Air Mini, as well. In past tests, it performed equally well in a 200-square-foot, 1,600-cubic-foot New York City bedroom. Finally, it’s easily the most affordable purifier of its capabilities we’ve ever found: Adding up the purchase price, the costs of 24/7 operation on medium, and the costs of annual filter changes, you’re looking at about $470 over five years (or less: we calculate electricity costs at New York’s rates, which are 50% above the national average). So we’re not trying to say that individually, on any particular metric, we would be number one. There is, however, a common mistake any first-time air purifier user should watch for: leaving the plastic wrapper on the filter. That noted, we’ve run the filters on another Blueair machine, the 211+, for up to a year 24/7 and found no meaningful degradation in performance. And the Winix is physically larger than the Coway, only comes in black, and to us is not as good-looking. I will not buy this again. It’s a derivation of an older technology, PCO (photocatalytic oxidation). On medium, where it produces a sleep-friendly 43.2 decibels, it achieved an impressive 92.6% reduction. Like many air purifiers, the Coway Mighty has an ionizing function in addition to its HEPA filtration. 81. We measure livability factors such as how much noise they make when running, as well as their long-term costs for energy consumption and replacement filters. 30. To get rid of viruses and bacteria, you’ll need a disinfectant cleaner. 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. In a dark room, the lamp can be a distraction, and we wish there was an option to shut it off on every setting, as you can with the Coway. What’s less clear is whether a HEPA purifier would catch the virus prior to the point of inhalation. The Inofia PM1320 claims to work in rooms as large as 800 square feet. And its running costs are much higher too. Here’s the takeaway: In the case of a nearby wildfire or other ongoing pollution crisis, where ambient local air conditions are continuously bad, keeping your air purifier on high is probably the best practice. 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. And when the machine is running, its on/off button emits a glow that you can’t turn off, so if you’re bothered by lights when trying to sleep (as guide author Tim Heffernan is), it can be an annoyance. The Levoit Vista 200 is a small-space machine, and it’s one of the best-selling purifiers on Amazon. That’s the main reason we’re lukewarm on smart purifiers in general. The filters fit fine, but they are not the pleated design. You’d use that setting in an extreme and ongoing pollution situation, such as when you’re dealing with a nearby wildfire. As we have for years, we normalized the data so that each machine’s peak represented the maximum particulate load it faced, specified as “100%,” and its overall performance represented its greatest reduction of particulates relative to that load. Like our other picks, it uses a true HEPA filter that efficiently captures particulate pollutants such as pollen and smoke. 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. Very disappointing. We will be testing the new, slightly more powerful Blue Pure 411+ once we have access to our New York office again. That raises another unanswered question about how effective an air purifier can be: What level of exposure to the virus causes an infection to begin with? It has also helped him make informed judgments on factors such as ease of maintenance and operation, the presence or lack of distracting noises or lights, and simple visual impact—the so-called little things that, if done wrong, can make what should be a nearly set-it-and-forget-it appliance into a daily annoyance. The two machines are similarly quiet, with the Airmega 400 registering 40 decibels on its “quiet”/high-medium setting and the Blue Pure 211+ measuring at 43 decibels on medium. 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 describe the results in What settings should you run an air purifier on? Keep doors and windows closed. The almost identical Winix AM80 lacks the AM90’s Wi-Fi capability and only comes in gray, but as of October 2020 is only available direct from Winix, where it costs $250. The Airmega 200M has a slightly more powerful motor, which accounts for its marginally better performance in our tests: In a half hour running on its highest setting, it reduced particulates by 99.4% on new filters, versus the Mighty’s 98.9%, and by 99.1% on old filters, versus the Mighty’s 98.9. And so—it’s fair to say that we needed to re-examine some of the language to make sure that it’s saying what we’re intending to say.”. In 2018, we tested two large-space contenders from Honeywell, the 50250-S and the HPA300. Furthermore, on October 5, 2020, the CDC changed its stance on how the virus is transmitted, and now says it “can be spread by exposure to virus in small droplets and particles that can linger in the air for minutes to hours.” In short, the CDC now acknowledges that the virus can spread via the air. CADR numbers in effect give the cubic feet per minute of perfectly pure air that a purifier can produce on its maximum setting. For the Molekule purifier, which uses a unique, non-HEPA method to remove particulates from the air, he took two measurements on each of the machine’s four settings (Silent, Auto, and Boost, corresponding to low, medium, and high fan speeds, and Dark plus Auto, in which the main purification method is off but the physical prefilter is in use). Regardless, the Air is weak. FURNACE FILTER QUALITY RATINGS [UPDATED for 2020] MERV 13 | BestAir Series 3500 & 3000 . Running on medium 24/7, it only consumes about $6 of electricity per year. The GermGuardian AC5900WCA was a stellar performer in our 2019 test, reducing particulates by 99.3% on high and 98% on medium. It’s extremely powerful, delivering our recommended 4 ACH (air changes per hour) in spaces as large as 650 square feet (assuming an 8-foot ceiling). if you need to clean the air in a small space—a bedroom, office, or dorm room up to about 200 square feet—it’s a solid choice. We really like the five different-colored prefilter “skins” you can choose from to cover the 211+, and you can also run the machine bare for a minimalist look. 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). As such, it posed a stiff test for all of the machines. The fibers in a HEPA filter capture airborne particulates in three basic ways (PDF). And the filters need to be replaced every eight months, at about $25 a pop. If your system uses a 1” filter, a 4” filter will not be able to fit the existing cabinet. In our office, even at a distance of 50 feet, the noise was intrusive during conversation.). With new filters, it reduced them by 99.3% and 99.2%, respectively. It has historically cost upwards of $750; we have seen it dip to near $500 at times, which is closer to being competitive with our other picks, but again: only if you really need to clean a vast space. When we tested it in October 2020, it delivered excellent performance on smoke particles, virtually identical to the Coway AP-1512HH. 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. When we found the CADR numbers in the manuals, we were alarmed. Tim placed the machines at the midpoint of the room, approximately 3 feet from the wall and away from any obstacles. Categories. We also tested the Molekule on its Dark setting, in which its light-based, primary PECO purification system is shut off and only its physical prefilter is in use; we set the airflow to Auto on the Dark tests. Can HEPA Air Purifiers Capture the Coronavirus? Tim conducted at least one pair of tests on each purifier: 30 minutes with the machine on its highest sub-50-decibel setting (about the upper limit of what we can consider comfortable for conversation), and 30 minutes with the machine on its absolute highest setting regardless of noise output. To remove allergens like pet hair and pollen, you’ll need a vacuum cleaner or dust mop. The Blueair Blue Pure 211+ is our choice among air purifiers for large spaces of up to 650 square feet, especially when it involves open floor plans or high ceilings. (On this model, you can tell that the ionizer is off when the button is unlit.) Updated October 2020 . And its five-year cost of ownership—about $1,150, including the up-front cost and the annual cost of electricity and replacement filters—is comparable to most large-space purifiers. It adds an air-quality sensor and, as a result, an automatic setting, in which the machine adjusts itself to address changing pollution levels. It is not true-HEPA rated but is certified by AHAM to have a clean air delivery rate (CADR) of 350 and performed exceptionally well in our testing, where we measure each purifier’s effectiveness at capturing HEPA-standard 0.3-micron particles. 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. The GermGuardian AC4100 “desktop” air purifier doesn’t meet our 4 ACH minimum for small spaces. In addition to these objective measures, we weigh the value each purifier offers, without setting a strict price limit within each room-size category. In early fall 2020, we received a few notes from readers about a pair of issues with their Coways. My humidifier is working much better now with these filters. In that case, we’ve learned that simply placing a US or Canadian quarter over the lamp completely blocks out its light, while letting you easily check the indicator if and when you want to. Their small footprints (10 by 8 inches for the Coway, 11 by 11 inches for the LG) belie the fact that they’re 32 and 30 inches tall, respectively—as tall as a kitchen counter—and so they take up a huge amount of visual space. The Airmega 200M shares the Mighty’s display-shutoff feature, which we value highly because it turns off the overly bright air-quality indicator lamp and makes this model much more conducive to bedroom use. But to qualify as great, it needs to be powerful enough to clean the air in a large living room or playroom, quiet and dark enough for you to sleep near it in a bedroom, and inexpensive enough that it’s reasonable to have several spread throughout your home. It has delivered exceptional air purification at the 0.3 micron HEPA standard in our testing. John Holecek conducted the lab tests in his San Diego facility, with professional-grade equipment used for atmospheric research (specifically a TSI 3080/3010 Scanning Mobility Particle Sizer and 3321 Aerodynamic Particle Sizer). Keep your purifier running. Finally, the running costs for the Coway Mighty are easily the lowest we’ve found for a purifier of its abilities. Find helpful customer reviews and review ratings for RPS BestAir Water Wick Filter for Emerson and Kenmore (16 Filters) at Amazon.com. Read more in How HEPA filters work. 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. The HealthMate’s performance comes at a price, however: Costing about $500 to $600 up front and averaging another $600 or so of electricity for five years of use, it’s the most expensive machine we recommend. Our review will show you some of the best cabin filters on the market that are decent replacements for your clogged-up cabin filter. And our past tests have indicated that the Coway Mighty, running on high for an hour, can reduce particulate pollution by nearly 100% in a typical bedroom, and then keep it there permanently on medium. The worst air purifiers we’ve ever tested. 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+. While we were researching and writing this guide, LG discontinued its Air Purifier Tower AS401WWA1 and PuriCare Air Purifier Round Console. In long-term use, we’ve repeatedly confirmed it works like new even with filters used continuously for a year or longer. (We use smoke to test them, in fact, so our picks directly reflect their ability to remove it.) The Mini needs a $75 replacement filter every six months; over five years (nine replacements), that works out to $675. Compare; Find My Store . The 200M and the Mighty are virtually identical in performance, but the 200M has an appearance that you may prefer, and it’s a good alternative if you find it at a lower price. To test our advice to run your purifier on high for an hour to create very clean air and thereafter on quiet/medium to maintain it, Tim ran a three-hour test in the 200-square-foot room, using the Coway AP-1512HH Mighty and our large-space pick at the time, the Coway Airmega 400. Melden. At the outset, he burned 15 matches to create extremely elevated particulate levels in the room, as though a fire were burning nearby. Yes. The Blueair Blue Pure 411, our former budget pick, performed well for a small-space purifier and is exceptionally energy efficient. The Winix also draws more electricity than the Coway: 13 watts versus 8.1 watts on the medium setting that we recommend for daily use. The Coway and Blueair scored 87.6% and 99.2%, respectively. To reduce them you need significant amounts of an adsorbent (usually activated carbon and/or alumina, which chemically bind to and neutralize the VOCs). When it comes to particulate pollution, the HM400 is a solid performer, reducing particulates to less than 20% of starting levels after 30 minutes on high in our 2017 real-world test (fourth best in our high-setting test) and to 50% (joint third best) on low. Hydroxyls are highly reactive, and they rapidly combine with nearby materials. And for such a powerful machine, the MA-112 is surprisingly easy on the ears, registering as “quiet” on its low, low-medium, and high-medium speeds (39, 42, and 47 decibels, respectively). Purchasing the most versatile air filter for home that is able to remove allergens and microparticles that pollute the air is a very hard task even though there are a great number of models to choose. That’s why we’ve always measured purifier performance at a considerable distance from the machines, outside of the path of the cleaned airflow. Best Cabin Air Filter Reviews … With a MERV rating of 16, you’ll get hospital grade filtration. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. LEBEN IST, WAS EINEM BEGEGNET, WÄHREND MAN AUF SEINE TRÄUME WARTET! And when we tested it during ongoing smoke conditions in a vast Los Angeles conference room of nearly 10,000 cubic feet—more than twice as large as the Coway Mighty’s specs would seemingly allow—it cut particulate pollution by almost 70% in an hour. For optimal performance, vacuum, wipe down, or rinse off the prefilter (it looks like a window screen or plastic netting) every month or so. The medium and low settings should be quiet enough to sleep near for most people. These differences are so small as to be functionally meaningless, and in any case favor the Airmega 200M.
