Health Effects
PFHxA (perfluorohexanoic acid) is a short-chain PFAS that may affect the liver, kidneys, and immune system. It is one of the most commonly detected PFAS in drinking water.
How PFHxA Gets Into Water
Widely used in food packaging, textiles, and as a replacement for longer-chain PFAS. Found in wastewater effluent and groundwater near industrial areas.
How to Remove PFHxA
Reverse osmosis and nanofiltration are the most effective. Activated carbon provides limited removal of short-chain PFAS like PFHxA.
Recommended: Reverse Osmosis (RO)
Reverse osmosis systems remove up to 99% of PFAS compounds. Recommended for homes with detected PFAS.
