Recommended Filtration

Heads up: sample concentrations in this system are above the EPA's numeric Maximum Contaminant Level. Utilities have until 2029 to install treatment if levels stay this high; in the meantime, standard pitcher filters (Brita, PUR) typically don't remove PFAS. The options below are certified for it.

Reverse Osmosis (Under-Sink)

Most effective at removing all detected PFAS compounds, including those exceeding MCLs.
