What is the best air purifier for most homes?

Best air purifier for most homes: Coway Airmega AP-1512HH Mighty. It is a strong default pick because it balances effective room-size cleaning, reasonable ongoing filter costs, simple controls, and a compact design that fits bedrooms, living rooms, and home offices.

If you have a larger open-plan space, choose the Blueair Blue Pure 211i Max or Coway Airmega 250 instead. If you want app controls and a modern smart-home feel, the Levoit Core 400S is the easier pick.
