A good air purifier can enhance your life by eliminating airborne allergens like pollen and mold spores and catching bacteria, viruses, and smoke from wildfires and other sources. Air purifiers are very simple equipment that is little more than a fan and a filter. However, an air purifier must be both well-engineered and creatively designed in addition to functioning effectively to be considered exceptional. That means, in our opinion, that the air purifier should be effective at cleaning the air in a sizable living or playroom, quiet and dark enough to allow you to sleep in a bedroom next to it, and reasonably enough so that you can afford to have multiple units placed about your house.

We’ve examined more than 50 different air purifiers over the past nine years, and since 2015, we’ve maintained that the excellent Coway Airmega AP-1512HH Mighty is the greatest of them all. Even yet, the Mighty’s performance is no longer as exceptional as it once was, and in recent years, several other air purifiers have come very close to meeting our exacting standards. If you prefer the design, price, or other qualities of one of our other top recommendations, know that their performance in purifying air is comparable to that of the Coway model.
