Affiliate disclosure
Room & Filter participates in the Amazon Associates program. If you buy through a link on this site, the site may earn a commission, at no extra cost to you.
What kind of links these are
Category-level search links only. This site does not publish ASINs, model verdicts, or prices , so an affiliate link here points at a search for the kind of product a page just explained how to size, never at “the best one”.
What the commission never changes
The published figures. Every number on this site comes from the EPA's Guide to Air Cleaners in the Home, cited on the page that uses it, above any affiliate link. The refusals, no published CADR for odours, MERV is not a room-size rating, exist for the reader, not for a checkout.
Technical details, because they matter
- • Affiliate anchors carry
rel="sponsored nofollow noopener"and open in a new tab. - • Links route through
/go/{key}, a logged 302 that is excluded from search indexing and never caches. - • The redirect only ever builds destinations from this site's own allow-listed table, never from the request URL.
- • No price is displayed anywhere on the site, per Amazon's terms.
