• Filter is only to be used with cold water.
• Filter usage must comply with all state and local laws.
• Testing was performed under standard laboratory conditions, actual performance may vary.
• Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.
• See owner’s manual for general installation conditions and needs plus manufacturer’s limited warranty.
All contaminants reduced by this filter are listed. Not all contaminants listed may be present in your water.
Does not remove all contaminants that may be present in tap water.
Testing Performed under NSF/ANSI Standards 42 and 53 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 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.
Not all water will contain contaminants listed. Testing performed under standard laboratory conditions; actual performance may vary. Filter usage
must comply with all state and local laws. Filter is only to be used with cold water. Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected water that
may contain filterable cysts. See installation guide for general installation conditions and needs as well as manufacturer’s limited warranty.
Tested and Certified by IAPMO R&T Lab and IAPMO R&T against NSF/ANSI 42 for the reduction of Chlorine,
Taste and Odor and Particulate Class I; NSF/ANSI 53 for the reduction of Cyst and Lead; and NSF/ANSI 372
for low lead compliance as verified and substantiated by test data.
