Performance Data Sheet:
The VRO-3U has been tested and certified by NSF International according to NSF/ANSI 42 and
58 and the VRO-4U has been tested and certified by NSF International according to NSF/ANSI
58 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 58. While testing was performed under standard laboratory conditions,
actual performance may vary.

Efficiency rating means the percentage of the influent water to the system that is available to the user as
reverse osmosis treated water under operating conditions that appropriate typical daily usage.
Recovery rating means the percentage of the influent water to the membrane portion of the system that is
available to the user as reverse osmosis treated water when the system is operated without a storage tank or
when the storage tank is bypassed.
