PFAS 'Forever Chemicals' in Tap Water: How to Choose a Certified Filter

What are PFAS 'Forever Chemicals'?

Per- and polyfluoroalkyl substances (PFAS) are synthetic industrial chemicals used in non-stick cookware, firefighting foam, and stain-resistant fabrics. Because their carbon-fluorine bonds do not break down in nature, they accumulate in groundwater and drinking supplies across the US.

New EPA Drinking Water Regulations for PFAS

The EPA established mandatory Maximum Contaminant Levels (MCLs) for PFOA and PFOS at **4.0 parts per trillion (ppt)**. Municipal water systems are actively upgrading treatment plants, but household filtration provides immediate protection.

Which Filters Remove PFAS?

Not all pitcher filters remove PFAS. To effectively eliminate PFAS from drinking water, choose:
1. **NSF 58 Certified Reverse Osmosis (RO) Systems** (Reduces 98%+ of PFAS).
2. **NSF 53 Certified Catalytic Activated Carbon Filters**.
