NOTE:
Substances reduced are not necessarily in your water. Filter must be maintained
according to manufacturer’s instructions, including replacement of filter cartridges.
WARNING:
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 waters that may contain filterable cysts.
Contact your area retailer or local water treatment professional for replacement cartridge
pricing.

Performance Data
Model US-640
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 treat-
ment needs.
This system has been tested according to NSF/ANSI 42 and 53 for reduction of the sub-
stances 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.
