Which water filters remove microplastics?
28 of the 96 water filters we track are certified to reduce microplastics (NSF/ANSI 401 listings). The lowest-priced is the Brita Elite faucet filter (faucet-mount, $32; about $54 a year in filters for 2 people). Counting a year of replacement filters, the cheapest to own is the Brita Denali 6-cup pitcher (Elite filter) ($76 the first year). 6 more claim it from brand-run lab tests only, which is not certification.
The EPA has no enforceable limit for microplastics in drinking water. No federal limit. Microplastics are one of four chemical groups on EPA's Draft Contaminant Candidate List 6 (announced April 2, 2026; FR April 6, 2026; comments closed June 5, 2026). CCL listing is not regulation. epa.gov Source note

Each row is a certifier listing for this exact product with microplastics in its reduction claims; the listing is linked. Yearly cost is replacement filters (plus drain water for RO) for 2 people, from each brand's filter prices and ratings.
Brand tests only, not certified (6)
These brands cite a lab report for microplastics, but no certifier lists the claim for the product. A lab report can be real; it is not an independent, ongoing certification with factory audits.

Common questions
Which water filters remove microplastics?
28 of the 96 water filters we track are certified to reduce microplastics (NSF/ANSI 401 listings). The lowest-priced is the Brita Elite faucet filter (faucet-mount, $32; about $54 a year in filters for 2 people). Counting a year of replacement filters, the cheapest to own is the Brita Denali 6-cup pitcher (Elite filter) ($76 the first year). 6 more claim it from brand-run lab tests only, which is not certification.
Is there a legal limit for microplastics in tap water?
The EPA has no enforceable limit for microplastics in drinking water. Do not imply health benefit; NSF article itself notes no clearly documented drinking-water health effects.
How do I know a filter really removes microplastics?
Look it up in the certifier's public database (NSF, WQA, IAPMO or CSA) under the exact model, and check that microplastics is in its list of reduction claims (usually under NSF/ANSI 401). "Tested to NSF standards" in an ad is not the same as a listing.
