Health Effects
PFPeA (perfluoropentanoic acid) is a short-chain PFAS compound. While its specific health effects are less studied than PFOA/PFOS, it may affect the liver and immune system. Like all PFAS, it does not break down naturally.
How PFPeA Gets Into Water
Byproduct of PFAS manufacturing and degradation of other PFAS compounds. Found in wastewater and groundwater near industrial facilities.
How to Remove PFPeA
Reverse osmosis and nanofiltration are the most effective removal methods for short-chain PFAS like PFPeA.
Recommended: Reverse Osmosis (RO)
Reverse osmosis systems remove up to 99% of PFAS compounds. Recommended for homes with detected PFAS.
