New ANSI Standard Looks At Shower Filtration

December 1, 2004
The American National Standards Institute has issued a new standard for shower filters. NSF/ANSI 177 (shower filtration systems - aesthetic effects) is a consensus standard for shower filters designed to demonstrate both performance and the safety of shower filtration products. The new standard: determines free available chlorine reduction to verify performance; evaluates product materials to ensure that they are safe; tests structural integrity to ensure product durability; and ensures that product literature claims are accurate.
