AO-US-100R is certified by WQA when used in AO-FF to NSF/
ANSI standards 42, 53, and 401 for the reduction claims
specified on the Performance Data Sheet and at
www.WQA.org.

Do not use with water that is microbiologically unsafe or of
unknown water quality without adequate disinfection before or
after the system.

Filter is only to be used
with cold water.

Filter usage must comply
with all state and local laws.

Testing was performed
under standard laboratory
conditions, actual
performance may vary.

Systems certified for cyst
reduction may be used on
disinfected waters that may
contain filterable cysts.

• All contaminants reduced by this filter are listed.
• Not all contaminants listed may be present in your water.
• Does not remove all contaminants that may be present in tap water.
• The contaminants covered in NSF/ANSI 401 have ben deemed as
incidental/emerging compounds and have been detected in drinking water
supplies at trace levels. These compounds can affect some consumers’
perception of drinking water quality.

This system has been tested according to NSF/ANSI 42, 53, & 401 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, 53, & 401.
