Tap water in the US contains detectable PFAS in over 45% of systems tested by the USGS. Plastic water bottles leach BPA, BPS, and microplastics — especially when heated. The average American gets a significant portion of their total plastic exposure from drinking water and beverage containers.
Why We Recommend This Product
Berkey's stainless steel design is appealing for chemical-conscious consumers. However, the lack of NSF/ANSI certification is a significant limitation — their PFAS removal claims are not independently verified. Good for many contaminants but not the best choice for PFAS removal.
