Per- and Polyfluoroalkyl Substances (PFAS)
Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals
used to make household products stain-resistant, waterproof and nonstick. PFAS are found in many products
like carpet, upholstery, cookware, food packaging and fire-fighting foam. Although many U.S. companies have
stopped using certain PFAS chemicals, they are still commonly used in foreign
products imported and sold in this country.
