Performance Data
Reverse Osmosis Filter System - Model WHAPSRO
IMPORTANT NOTICE:
Read this performance data and compare the capabilities of this unit with your actual water
treatment needs. It is recommended that, before purchasing a water treatment unit, you have your water supply
tested to determine your actual water treatment needs. This filter system is designed to be used for the reduction of
the substances listed below. Do not use where water is microbiologically unsafe or of unknown quality, without ade-
quate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected water
that may contain filterable cysts. This system has been tested for the treatment of water containing pentavalent
arsenic (also known as As (V), As (+5), or arsenate) at concentrations of 0.30 mg/L or less. This system reduces
pentavalent arsenic, but may not reduce other forms of arsenic. This system shall be used on water supplies con-
taining a detectable free chlorine residual at the system inlet or on water supplies that have been demonstrated to
contain only pentavalent arsenic. Treatment with chloramine (combined chlorine) is not sufficient to ensure complete
conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section on page 26 for further
information. While testing was performed under standard laboratory conditions, actual performance of this system
may vary based on local water conditions. Some or all of the contaminants reduced by this unit may not be in your
water supply. See elsewhere in this owner’s manual for further instructions on filter replacement, system installation,
operating procedures, and warranty. The maintenance instructions must be followed for the product to perform as
indicated below.
General Information
This product is an undercounter system that filters and stores quality drinking water ready for use. It contains a car-
bon sediment filter, RO membrane, and an activated carbon post filter. This system has been tested according to
NSF/ANSI 58 and 42 for reduction of substances listed below. The concentration of the indicated substances in
water entering the systems were reduced to a concentration less than or equal to the permissible limit for water leav-
ing the system, as specified in NSF/ANSI 58. The testing was performed using spiked chlorine free deionized water
with ≤1 NTU turbidity, 7.5 ± 0.5 pH, 25 ±1°C, and 1μS/cm conductivity.
Maintenance
Replacement filter prices may vary. Estimated costs of replacement filter elements (part number WHEERF), or
replacement membranes (part number WHEERM), range from $39 to $59.

A carbon prefilter is part of this system to protect the reverse osmosis membrane from
deterioration should there be chlorine in the supply water. This reverse osmosis system
contains a replaceable treatment component critical for effective reduction of TDS. The
product water shall be tested periodically to verify that the system is performing satisfactorily.
