Toppen system explanation

NSF / ANSI testing

EPA · PFAS · UCMR 6

Forever Chemicals: PFOA and PFOS. Studies indicate exposure over certain levels may result in adverse health effects, including developmental effects, cancer, liver effects, immune effects, thyroid effects and cholesterol changes. GAC has been shown to effectively remove PFAS from drinking water.

The EPA’s proposed UCMR 6 mandates monitoring for 30 unregulated contaminants from 2028 to 2030. Microplastics were excluded because EPA determined there is no validated national analytical method. Pharmaceuticals were also not included.
