Reverse Osmosis Filter System

Model WHER25

IMPORTANT NOTICE: Read this Performance Data Sheet 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 adequate disinfection

before or after the system. Systems certified for cyst reduction may be used on disinfected water

that may contain filterable cysts. This system is acceptable for treatment of influent concentrations

of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N and are certified

for nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater.

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 containing a detectable free chlorine residual at the system inlet or on water supplies that

have been demonstrated to contain only pentavalent arsenic.

(combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to

pentavalent arsenic. Please see the Arsenic Facts section of the Performance Data Sheet 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 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 carbon sediment filter, RO membrane, and an activated carbon post filter. The faucet

indicator monitors the length of time the filter has been installed and will flash amber

continuously; indicating the filters and battery need to be replaced. 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 leaving 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. For estimated costs of replacement filter elements part

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.
