Health Effects
PFBS (perfluorobutane sulfonic acid) is a short-chain PFAS that can affect the thyroid, kidneys, and reproductive system. While it leaves the body faster than long-chain PFAS, it is still persistent in the environment.
How PFBS Gets Into Water
Used as a replacement for PFOS in industrial applications. Found near manufacturing facilities, wastewater treatment plants, and areas where firefighting foam was used.
How to Remove PFBS
Reverse osmosis and nanofiltration are the most effective. Some activated carbon filters can reduce PFBS levels, but RO is recommended for consistent removal.
Recommended: Reverse Osmosis (RO)
Reverse osmosis systems remove up to 99% of PFAS compounds. Recommended for homes with detected PFAS.
