If the AM90 is unavailable, the otherwise identical Winix AM80 is worth considering. It comes only in dark gray, lacks Wi-Fi connectivity, and uses a one-year VOC filter in contrast to the AM90’s three-month filter.
The 200M and the AP-1512HH are virtually identical in performance, but the 200M has an appearance that you may prefer, and it’s a great alternative if you find it at a lower price. You can also use the air purifier for aromatherapy purposes by adding four to five drops of essential oil. “I’ve only had this for about a week and I’ve already noticed a difference. I’m not as stuffy as I used to be when I wake up in the morning, and I sneeze a lot less,” one reviewer noted. It affects our lungs, blood circulation, heart, and overall physical health. But it’s possible that the air inside your home is dirtier than you think.
It’s not particularly power-hungry, unlike the Air Pro, but on its medium setting it still draws more electricity than the far more capable Coway Mighty, our top pick among purifiers and a machine capable of keeping the air clean in a far larger space. Using ACH to categorize air purifiers overcomes a common problem in the way manufacturers rate their air purifiers in their advertising. Most offer instead a square-footage rating, presumably because it’s easy for a prospective customer to take their room’s dimensions and then pick a purifier accordingly. But square-footage claims are essentially meaningless—if you’re comparing two rooms with very different ceiling heights and thus different volumes, for example.
Over a longer timeframe—and especially if kept running on medium 24/7, as we recommend for all our purifier picks—they will create and maintain very clean air in a typical home office or bedroom. In our tests, on high, it reduced a heavy load of 0.3-micron smoke particles by 99.9% in 30 minutes; on medium, it reduced them by 94.2%. Both results indicate that it’s a highly efficient purifier, in the same league as the Coway Airmega AP-1512HH Mighty and our Winix picks.

Griner will describe “her stark and surreal time living in a foreign prison and the terrifying aspects of day-to-day life in a women’s penal colony,” her publisher said. For National Pet Day, we explore some of the pros and cons a pet can have for your health. Fire officials said the owner of an abandoned Hoffco factory had been cited multiple times for potential fire hazards and that “it wasn’t a matter of if, it was a matter of when this was going to happen.” The Levoit H132 scores an impressive 4.7 out of five stars on Home Depot.
You would use that setting in an extreme and ongoing pollution situation, such as when you’re dealing with smoke from a nearby fire. But on their highest setting, most air purifiers are too loud—above 50 decibels, where we draw the line—to be tolerable as a background for conversation, sleep, or TV watching. So we always confirm
whether our picks can keep the air clean on their medium or quiet setting in a room of the recommended size. There’s also a timer and pollution sensor,” experts wrote earlier this year. This Levoit air purifier has a three-stage filtration system with a pre-filter, a True HEPA filter and a high-efficiency activated carbon filter.
Levoit products often rank highly amongst independent product reviews, and each unit we’ve tested has impressed us. From gauging customer feedback online, Levoit is often praised for its helpful customer support, with centers in the U.S., Europe and Asia. What’s more, Levoit offers special discounts through VerifyPass to active military personnel, veterans, medical staff, first responders, and teachers, which is a big plus from our point of view. With 3-stage filtration, this unit was designed for use in spaces up to 129 ft², despite only having a CADR rating of 40 CFM. One of the significant differences of this model is that it uses one-button control, unlike the others with a multi-button control panel.
Yet it costs far more up front, with a price tag of $400 versus a usual $300 for that Blueair model. Within 30 minutes, the Coway Airmega 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%. In past tests, it performed equally well in a 200-square-foot, 1,600-cubic-foot New York bedroom.
Based on its specs, we determined that it’s appropriate for rooms of just 287 square feet (where its CADR numbers result in our recommended 4 air changes per hour). The Winix A230, a small-space purifier suited for bedrooms or offices, performed well in our tests—seemingly too well for such a small machine. Afterward, we realized that we had inadvertently tested it with its ionizer function on, and we recommend against ionizers because of their (admittedly small) production of ozone.
