The best air purifier is the one whose smoke CADR fits your room. For most bedrooms and living rooms up to about 360 sq ft, start with the Coway Airmega Mighty line. Nine picks covering rooms from 140 sq ft to over 650 sq ft, each with honest fit and caveats.
Black Friday 2026 lands on November 27. This guide covers 11 air purifiers worth watching β from desk units to open-plan models β with verified CADR figures, room-size guidance, and tips for spotting a genuine discount.
The Levoit Vital 200S is a strong value pick for bedrooms and living rooms up to 388 sq ft. Independent tests confirm its 250 CFM rating β but the filter is not sold as certified True HEPA, and quiet speeds deliver about half the top-speed airflow.
