The H2O-DWCFL100 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 specied in NSF/ANSI 42 and 53, and
substantiated by test data. This system is certied to NSF/ANSI standard 372 for ‘lead free’ compliance.

GENERAL USE CONDITIONS
1: System to be used with municipal or well water sources treated and tested on regular basis to insure bacteriological safe
quality. DO NOT use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before
or after the system. While testing was performed under standard laboratory conditions, actual performance may vary.
Systems certied for cyst reduction may be used on disinfected waters that may contain lterable cysts.

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 certied for cyst
reduction may be used on disinfected water that may contain lterable cysts.
