What to Do About PFAS in Huntsville Water
- Install a reverse osmosis system (most effective — removes 90%+ of PFAS)
- Granular activated carbon (GAC) filters remove some PFAS compounds
- Look for NSF 53 or NSF 58 certification specifically tested for PFAS
- Pitcher filters with activated carbon provide partial reduction
Look for filters certified under NSF 53 / NSF 58 for pfas removal.
