NSF/ANSI 58 is the US national standard for drinking water treatment systems using RO reverse osmosis technology, certified by the National Sanitation Foundation (NSF) of the US government and established by the American National Standards Institute (ANSI), also of the US government. This is one of the world's leading stringent standards for the safety, hygiene and performance of water filtration equipment. This standard sets strict requirements for the ability to filter out harmful substances to users such as total dissolved solids (TDS) and remove dangerous pollutants such as lead, arsenic, nitrate, volatile organic compounds (VOCs) ...
