The Best Air Purifier

Air purifiers are fundamentally simple machines—little more than a fan and a filter—but a great one can improve your life by reducing airborne allergens such as pollen and mold spores and capturing bacteria, viruses, and smoke from wildfires and other sources. To qualify as great, however, an air purifier doesn’t just need to work well; it also needs to be robustly engineered and thoughtfully designed. To us, that means the air purifier should be powerful enough to clean the air in a large living room or playroom, quiet and dark enough for you to sleep near the machine in a bedroom, and inexpensive enough that it’s reasonable to have several units spread throughout your home. After nine years, during which we’ve tested more than 50 different air purifiers, we believe that the exceptional Coway Airmega AP-1512HH Mighty is the best among them—as we have since 2015. That said, as strong as the Mighty is, its performance is not as singular as it once was, and in recent years many other air purifiers have closely approached our high standards. If you prefer the looks, cost, or other features of our also-great picks, know that they match this Coway model in purifying performance.

We recommend
Cabiclean HEPA Carbon Replacement Filter Pack, a solid third-party replacement filter set

Another good choice
Coway Airmega 200M, different look, same great performance

Coway Airmega 200M

Different look, same great performance
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.
Another good choice
Winix 5500-2, exceptional performance, brutalist design

Winix 5500-2

Exceptional performance, brutalist design
The Winix 5500-2 is an exceptional performer, but its stark look, lack of a display shutoff, and slightly higher electrical use are minor shortcomings.
Another good choice
Winix AM90, exceptional performance, modern style

Winix AM90

Exceptional performance, modern style
Essentially a 5500-2 in a sleeker housing, the AM90 also shares that model’s few shortcomings, namely higher energy consumption and the absence of a display shutoff.
Another good choice
Blueair Blue Pure 311 Auto, top performance, pleasing form

Blueair Blue Pure 311 Auto

Top performance, pleasing form
Delivering exceptional performance in an attractive form, the Blue Pure 311 Auto suffers only from higher running costs and a lack of a display shutoff.
Another good choice
Levoit Core 400S, great performance plus voice control

Levoit Core 400S

Great performance plus voice control
As effective as our top pick, the Coway AP-1512HH, but usually a bit more expensive to run, the Levoit Core 400S adds voice control via an app, Amazon Alexa, or Google Assistant.
Another good choice
Blueair Blue Pure 211+, a stellar performer for larger rooms

Blueair Blue Pure 211+

A stellar performer for larger rooms
The Blue Pure 211+ aced our tests, and its ability to move extremely high volumes of air makes it our pick for large spaces.

Small, effective, and attractive
In a small bedroom, dorm room, or office, the compact and affordable Levoit Core 300 performs extremely well and looks great.
