Does reverse osmosis remove pfas

How do select RO systems reduce PFOA and other PFAS from home water? Reverse osmosis systems use a powerful 3-stage filtration process that moves water through a carbon pre-filter, a semipermeable membrane and a post-filter. This advanced water filtration process relies on the sophisticated, semipermeable membrane and high-performance …

You often also find activated carbon filters in reverse osmosis systems, which combine carbon filtration with reverse osmosis membranes. Reverse osmosis filters can remove up to 99.9% of all total dissolved solids, including PFAS, so they enhance the PFAS reduction capabilities of a carbon filter.To find products certified for reduction of PFOA and PFOS by NSF, visit NSF's certification listings or contact the NSF consumer information team at [email protected] or +1.800.673.8010.
