Despite the findings of these new investigations, a 2008 study by the Minnesota Department of Health (MDH) found that the use of carbon block filters (Like our Multipure filters) were effective in treating the presence of PFCs.

Recent studies published in Environmental Science and Technology Letters (ESTL)and Environmental Health Perspectives (EHP) examine the presence and effects of drinking water contamination by poly- and perfluoroalkyl substances (PFAS). These chemicals, part of a broader category of substances known as perfluorochemicals (PFC), have been linked to negative effects including high cholesterol, hormone suppression, cancer, and decreased child immune system health.
