SYSTEM RATING

Average T.D.S. Reduction: 93%

System Production: 14 gallons per day (53 liters per day) Recovery Rating: 38% Efﬁciency Rating: 22%

Measured at 50 psig, 77°±2°F, 750±40 mg/L T.D.S., per section 6 of NSF/ANSI standard 58 product water to pressurized

storage tank. 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. 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 approximate typical daily usage. Sodium Chloride was used as a

surrogate for T.D.S. System rating determined by laboratory testing at NSF.

MEMBRANE RATING

Membrane Production: 41-53 gallons per day (155–201 liters per day) Membrane T.D.S. Reduction: 96% minimum

Note: Measured at industry standard condition of 65 psig, 77°F, 250 ppm T.D.S., and discharging to atmosphere. Actual system

production and contaminant reduction will depend upon water temperature, pressure, pH and T.D.S. level, membrane variation

and usage pattern.

(The cyst reduction claim includes oocysts of Cryptosporidium and cysts of Giardia and Entamoeba.)

Water supplies that exceed limits for Hardness,

Iron, Manganese and Hydrogen Sulﬁde require

pretreatment.

REDUCTION PERFORMANCE CLAIMS:

This system has been tested according to NSF/ANSI 58 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 58. Testing was performed under standard laboratory conditions. Actual performance may vary.

Results

Caution: 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 water that may contain

ﬁlterable cysts.

Test Parameters:

pH 7.5±0.5

Turbidity < 1 NTU

Temperature 77°±2° F

Pressure 50 psig

2 Average based upon actual test data.

3 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 remove other forms of arsenic. This

system is to 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. Treatment

with chloramine (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.

4 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 is certiﬁed for nitrate/nitrite reduction only for

water supplies with a pressure of 280 kPa (40 psig) or greater.

5 The reduction of Radium was veriﬁed by using Barium as a surrogate

under NSF/ANSI Standard 58.
