How evidence affected scoring

Applicable score inputs require claim-linked evidence under the frozen category rubric. Missing or stale evidence is handled by the rubric's predeclared rule; it is never guessed or replaced by a more favorable weight. Evidence coverage and confidence are reported separately from the organic score.

Evidence gaps remain recorded for: Oreck, Panasonic, Philips.

No source detail requires additional buyer verification in this publication.

Claim-linked evidence

Independent standardized testing materially corroborates the representative performance, noise/usability, ownership-value, and transparency ratings for AirDoctor; it does not prove that every model performs identically.

HouseFresh independently bought and tested the AirDoctor 3000/3500 platform, recording 14-16 minute particle clearing, 40.2-63.6 dB sound, strong auto mode, and higher genuine-filter costs than mainstream value brands.

Independent standardized testing materially corroborates the representative performance, noise/usability, ownership-value, and transparency ratings for AirDoctor; it does not prove that every model performs identically.

AirDoctor's current U.S. collection lists five models from compact through extra-large spaces, with current prices from $399 to $999. Representative pages publish smoke CADR, bounded four-air-change room sizing, HEPA and carbon stages, filter alerts, and optional app-connected smart variants.
