This Standard establishes minimum health effects requirements for the chemical contaminants and impurities indirectly imparted to drinking water from products, components, and materials used in drinking water systems. Products certified to NSF/ANSI/CAN 61 comply with the health effects criteria in NSF/ANSI/CAN 600. This Standard does not establish performance, taste, odor, or microbial growth support requirements for drinking water systems products, components, or materials. Drinking Water Treatment Products certified to NSF/ANSI/CAN 61 have not been tested or evaluated for contaminant reduction performance. Contaminant reduction testing and certification claims shall be assessed against the industry's drinking water treatment unit standards.
