Chemical, Mechanical Reduction Filter
This system has been tested according to NSF/ANSI Standards 42 and 53 for the 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 and 53.
Capacity: 40 gallons (151 liters) depending on local water conditions
System tested and certified by NSF International against NSF/ANSI
Standard 42 for the reduction of Chlorine Taste and Odor, Particulate
Nominal Class I and against NSF/ANSI Standard 53 for the reduction of
Lead, Mercury, Asbestos, Cadmium, MTBE, Toxaphene, VOC, Cyst,
Turbidity.
