Testing performed by IAPMO R& T against NSF/ANSI Standards 42, 53, 58, 401, and NSF Protocol P473 & P231 and in accordance with the California Department of Health Services
Drinking Water Treatment Device Program. This system has been tested according to NSF/ANSI 42, 53, 58, 401 & P473 for reduction of the substances listed below. The concentration
of the indicated substances in water entering the system was reduced to a concentration less than or equal to the permissible limit for water leaving the system, as specified in NSF/
ANSI 42, 53, 58,401, P473 & P231.
