Water filters certified to remove PFOS
'Forever chemical.' 2024 EPA MCL = 4 ppt. Immune suppression, thyroid, cholesterol, developmental effects.
"Certified" means the model is listed in the NSF, WQA, or IAPMO public database as reducing PFOS — not just "tested to" a standard.
Pick the path that fits you
You can start cheap with a no-install filter, or solve it permanently with an installed system that costs far less per gallon over time. Both options below are certified to reduce PFOS.
