About Air Filter Lookup

Air Filter Lookup is an independent air purifier replacement filter lookup covering Blueair, Coway, GermGuardian, Honeywell, Levoit, Medify Air, and Winix. It answers one question fast: which filter fits my purifier?

How we verify every match

Every published part number, model compatibility match, and care schedule is tied to a cited official manufacturer source, with the date it was checked. If the manufacturer's page doesn't state a fit, we don't list it. Similar model names, seller titles, and look-alike photos never count as evidence.

How we make money

Sponsored eBay links pay us a small commission when you buy. Links to manufacturer pages are never paid. See the affiliate disclosure.

Independence

Air Filter Lookup is not affiliated with, sponsored by, or endorsed by any manufacturer, marketplace, or retailer listed on the site. Compatibility data is presented for informational purposes. Always verify the model label on your unit and review the cited source before purchasing.

Missing a model?

We add models only after confirming them against the manufacturer's own product page. Until then, the official Blueair, Coway, GermGuardian, Honeywell, Levoit, Medify Air, and Winix sites are the best place to check.
