What is NSF Standard 61?
The NSF Water Distribution Systems Program is responsible for the Certification of drinking water treatment chemicals and drinking water system components to ensure that these products do not contribute contaminants to drinking water that could cause adverse health effects.
NSF Standard 61 Drinking Water System Components – Health Effects is the nationally recognized health effects standard for all devices, components and materials which contact drinking water.
