CONTAMINANT REMOVAL DATA IMPORTANT NOTICE:
Read this Performance Data Sheet and compare the capabilities of this unit with your actual
water treatment needs. It is recommended that, before purchasing a water treatment unit, you
have your water supply tested to determine your actual water treatment needs.
Performance testing conducted by NSF International. These systems have been tested according
to NSF Standard 53 and 42 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 the water leaving the system, as specified in NSF Standard
53 and Standard 42.
Testing was performed under standard laboratory conditions; actual performance may vary.
