Tested and certified by NSF International against NSF/ANSI Standard 42 for the reduction of Chlorine Taste & Odor,
Particulate Class I; and against NSF/ANSI Standard 53 for the reduction of Lead, Mercury, Atrazine, Benzene, Carbofuran,
1,4-dichlorobenzene, Lindane, Toxaphene, Turbidity, Cysts and Asbestos.
This system has been tested according to NSF/ANSI 42/53 for reduc-
tion of the substances listed below. The concentration of the indicated
substances in water entering the system was reduced to a concentra-
tion less than or equal to the permissible limit for water leaving the
system, as specified in NSF/ANSI 42/53.
