ENERGY STAR Most Efficient air purifiers
Ranking criteria: listing flagged "meets Most Efficient criteria" in ENERGY STAR data; grouped by smoke CADR class; ranked by smoke CADR per watt within each class. Data: ENERGY STAR certification records (retrieved 2026-10-17); electricity estimates use EIA rates (July 2026 (preliminary)). These rankings are calculated from published data only. They are not hands-on tests, and noise, filter price and build quality are not considered (no such data in ENERGY STAR records).
66 of 247 listings carry the flag (some designs appear under several brand names).
