Which water filters remove chromium 6?

The lowest-priced is the ZeroWater 10-cup pitcher (pitcher, $38; about $272 a year in filters for 2 people). 8 more claim it from brand-run lab tests only, which is not certification.
The EPA legal limit (MCL) for chromium 6 in public drinking water is 0.1 mg/L (total chromium). No federal chromium-6-specific MCL. Federal MCL 0.1 mg/L applies to total chromium (all forms). EPA is developing an IRIS assessment before deciding on a Cr-6 rule (EPA chromium page updated Mar 4, 2026). epa.gov Source note

Common questions
Which water filters remove chromium 6?
7 of the 96 current water filters we track are certified to reduce chromium 6 (NSF/ANSI 53 and NSF/ANSI 58 listings). The lowest-priced is the ZeroWater 10-cup pitcher (pitcher, $38; about $272 a year in filters for 2 people). 8 more claim it from brand-run lab tests only, which is not certification.
Is there a legal limit for chromium 6 in tap water?
The EPA legal limit (MCL) for chromium 6 in public drinking water is 0.1 mg/L (total chromium). Record as 'no federal Cr-6 limit; total chromium 0.1 mg/L'.
How do I know a filter really removes chromium 6?
Look it up in the certifier's public database (NSF, WQA, IAPMO or CSA) under the exact model, and check that chromium 6 is in its list of reduction claims (usually under NSF/ANSI 53 or 58). "Tested to NSF standards" in an ad is not the same as a listing.
