How We Compare Air Purifiers

Every comparison uses the same data framework: AHAM-verified smoke CADR as the primary performance metric, Beast Score composite rating, noise level at each fan speed, annual filter replacement cost and five-year total ownership cost. Where a brand does not submit to AHAM testing, we disclose that clearly and note that CADR figures are self-reported.

See our scoring methodology for the full framework. For buying recommendations, see our best overall picks.
