Performance Data
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 
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.

Testing was performed under standard laboratory conditions, actual performance may vary.
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. 
NOTE: Substances reduced are not necessarily in your water. 
Filter must be maintained according to manufacturer’s instructions, 
including replacement of filter cartridges.
