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.

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.

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.
