QUESTIONS (FAQ)
1. What Does the System Do?
This System has been tested to significantly
physically block pathogens including bacteria,
viruses, and cysts from your water. The pore
size on the surface of the ultrafilter membrane
is 0.02 microns nominal. The System has been
certified by the National Sanitation Foundation
(NSF) for NSF 42 and 53 (aesthetic and health
claims) for the removal of Cysts, Turbidity,
Particulates and Chlorine. Further test results
from BioVir Laboratories in California include
Bacteria and Virus reduction performance.
Please refer to C. CERTIFICATION for more

2. How does the System work?
2.1 Filtering- When a household water fixture is
turned on, the water pressure forces unfiltered
water into the Prefilter Housing.
(1) Larger particles (and chlorine when using the
Carbon Prefilter) are removed as the water
passes from the outside of the Prefilter to the
inside.
(2) The prefiltered water then passes down into
the System to the membrane chamber.
(3) In the membrane chamber, the water travels
through membrane pores from the outside of
the hollow fiber membrane to the inside,
leaving behind unwanted particles such as
bacteria, parasites and certain viruses.
(4) The filtered water then travels through the
household piping, to the household fixture that
is being used.
2.2 Automatic Cleaning Cycle – The System
uses 2 methods to clean its membrane: a)
flushing and b) draining. The Controller
automatically executes a cleaning sequence
consisting of a number of flushes and drains to
clean the membrane. System cleaning may be
performed multiple times per day, up to 24
times. For choices of cleaning sequences and
intervals, refer to the Controller Settings
section under
INSTRUCTIONS. Water pressure inside the
dwelling will be significantly reduced during
System cleaning.
2.3 Flushing – Flushing includes a Front-flush
and a Back-flush. Systems that are installed in
municipal, cistern, or ground water sources
may use the flushing method to control the
fouling rate of the membrane.
(5) Front flush – The Controller opens the Drain
Solenoid Valve. The water supply line pressure
causes an inrush of water into the System,
scouring the surfaces of the membrane and
expelling impurities through the drain.
(6) Back-Flush – At the same time, the air
bladder inside the Backpulse Tank expands
rapidly, pushing clean water out of the
membrane surfaces from the hollow cores. This
action dislodges and pushes out impurities
trapped inside the membrane pores. Impurities
are then expelled out of the System through the
drain port.
2.4 Draining – Systems that are installed in
surface water sources must use the draining
method in addition to the flushing method to
control the fouling rate of the membrane.
During draining, the Controller closes the Inlet
Solenoid Valve and opens the Drain Solenoid
Valve, allowing water to be completely drained
out of the System.
3. Where should the System be
installed?
The System is installed inside the home at the
point where water enters the house so that
filtered water is provided from every tap. In
order to allow only indoor water to be treated, a
dedicated line should be installed from the inlet
of the System to all external taps for pool or hot
tub makeup valves and irrigation systems.
Reducing the volume of water filtered will assist
in prolonging the life of the System membrane.
