How compatibility is verified

Every match is backed by a recorded source

A filter appears on a purifier page only when a compatibility record links the two and that record has been marked verified against a source, normally the manufacturer's own product page or manual. Each match shows its fit type, an evidence summary, the date it was last verified and a link to the supporting source.

Fit types are not interchangeable

Official OEM
The purifier's own manufacturer sells or documents this filter for the model.
Manufacturer-approved
The manufacturer names the filter as suitable, though it may be produced under another label.
Third-party compatible
A non-OEM filter with documented evidence of fit. Performance and warranty terms can differ from the original part.

Similar dimensions do not prove compatibility

Matching sizes, similar part numbers or similar product names are never treated as evidence. A filter can be the same size and still seal incorrectly, block airflow or trigger filter-reset errors. If we have no verified evidence, we show nothing rather than a guess.

Check your exact model number

Manufacturers frequently sell variants that look identical but take different filters. Read the model number from the rating label on your unit and match every character, including hyphens and suffix letters, before ordering.

Prices and availability change

Seller prices are recorded with the date they were last checked and are shown for orientation only. Confirm the current price and stock on the seller's page. Where a purchase link is an affiliate link, it is labeled as such on the offer.
