Best Water Filter for PFAS and Forever Chemicals (2026)

PFAS are a family of synthetic chemicals that don't break down in the environment. In 2024 EPA set enforceable limits of 4 parts per trillion for PFOA and PFOS in drinking water. Utilities have until the end of the decade to comply, so many are still above that level today.

EPA's most recent nationwide testing (UCMR 5) found PFAS in about a third of the water systems it sampled. You can look up your own utility's results with the address checker on this site.

What works

  • Reverse osmosis: the most effective home option, typically removing 90%+ of PFAS
  • Activated carbon certified to NSF/ANSI 53 for PFOA/PFOS: a good lower-cost option
  • Look for NSF/ANSI 58 (RO) or NSF/ANSI 53 with a PFOA/PFOS claim on the certifier's listing

What doesn't

  • Boiling water (it concentrates PFAS)
  • Filters certified only to NSF/ANSI 42 (taste and odor) or NSF/ANSI 372 (lead-free materials)
  • Water softeners

What is the EPA limit for PFAS in drinking water?

EPA's enforceable limit (MCL) is 4.0 parts per trillion each for PFOA and PFOS. Utilities must comply by the end of the decade.
