Air Purifier CADR Check

Air purifiers with identical results under different brand names

Ranking criteria: groups of listings from two or more brand names whose smoke, dust and pollen CADR and annual kWh are all identical in ENERGY STAR data. Matching numbers strongly suggest a shared design (often the same ENERGY STAR partner), but we do not claim the products are identical in every respect. 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).

Why it matters: if two listings share results, compare price, warranty and filter availability, since the certified performance is the same.
