Important Notice:
Read this performance data and compare the capabilities of this
system with your actual water treatment needs. It is recommended that, before
installing a water treatment system, you have your water supply tested to determine
your actual water treatment needs.
This system has been tested according to NSF/ANSI 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
