As of October 22, 2026, 19 air purifiers we track are sized for rooms of 350 sq ft or more, about a living room, by their makers' figures at 4.8 air changes an hour: six from Winix, five each from Levoit and Coway, two from Blueair and one from Medify. Stated room sizes run from 358 sq ft on the Levoit Core 400S-P to 684 sq ft on the Coway Airmega 450. All six Winix models name a True HEPA filter, and 11 of the 19 state app control. We use 4.8 air changes an hour, AHAM's basis, for every purifier, and convert Coway's figures where Coway prints none at that rate.
