Toxic PFAS Leach Through Most In-Home Drinking Water Filters
Filters on refrigerator doors, pitcher-style filters, and whole-house filtration systems might function differently overall, but they have one thing in common: they might not be removing all toxic drinking water contaminants. Toxic PFAS, dubbed “forever chemicals,” persist in the environment indefinitely and accumulate in the human body. 99.9 percent of humans worldwide have PFAS in their bloodstreams. Duke and North Carolina State University scientists found that most filters are only partially effective in removing PFAS. Research suggests that several filters, if not properly maintained, can lead to even higher levels. PFAS have known health impacts and are a widespread presence in the environment, especially in drinking water. Exposure to these toxic chemicals is associated with various cancers, low birth weight in babies, thyroid disease, impaired immune function, and other health disorders. PFAS can also affect reproductive and developmental health in mothers and c...
