Moderate Exposure Risk — Why This Product Category Matters

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.
