Health Effects
PFHpA (perfluoroheptanoic acid) is a medium-chain PFAS that may affect liver function and the immune system. Research on its specific health effects is still emerging, but like all PFAS, it does not break down naturally.
How PFHpA Gets Into Water
Found near industrial facilities, wastewater treatment plants, and areas contaminated by firefighting foam. Also present in some food packaging and consumer products.
How to Remove PFHpA
Reverse osmosis is the most reliable removal method. Activated carbon filters can reduce levels but may not remove PFHpA completely.
Recommended: Reverse Osmosis (RO)
Reverse osmosis systems remove up to 99% of PFAS compounds. Recommended for homes with detected PFAS.
