Coway Airmega AP-1512HH Mighty Air Purifier

The Coway Airmega AP-1512HH Mighty has been Wirecutter's top-rated air purifier for a decade — and for good reason. The 4-stage filtration system removes 99.97% of particles as small as 0.3 microns, including dust, pollen, smoke, and pet dander. The built-in air quality sensor automatically adjusts fan speed in real time, while Eco Mode saves energy by shutting off when air is clean. Compact enough for any room, powerful enough for up to 361 sq ft.
