NSF minimum percent reduction requirement. Acceptance level for this substance is based on percent
reduction rather than maximum effluent concentration

Tested by Spectrum Labs, a qualified independent laboratory, against accepted industry protocol.
8
There is no maximum permissible effluent concentration for this substance because it is not included in the
chemical reduction claims listed in NSF Standard 58. The maximum effluent concentrations listed were
established by Spectrum Labs and are based on one third of the target influent.
9
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 daily usage.
10
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 by-passed.

Arsenic Fact Sheet
Background
Arsenic (abbreviated As) can occur naturally in well water. There are two forms of arsenic: pentavalent
arsenic (also called As (V), As (+5), and arsenate) and trivalent arsenic (also called As(III), As(+3), and
arsenite). Although both forms are potentially harmful to human health, trivalent arsenic is considered
more harmful than pentavalent arsenic. In well water, arsenic may be pentavalent, trivalent, or a
combination of both. Additional information about arsenic in water can be found on the Internet at the
U.S. Environmental Protection Agency (USEPA) website:www.epa.gov/safewater/arsenic.html.
Testing Your Water
Arsenic in water has no color, taste or odor. It must be measured by a lab test. Public water utilities must
have their water tested for arsenic. You can get the results from your water utility. If you have your own
well, you can have the water tested. The local health department or the state environmental health agency
can provide a list of certified labs. The cost is typically $15 to $30.
Pentavalent vs.Trivalent Arsenic Removal
These systems are very effective at reducing pentavalent arsenic from drinking water. These models were
tested in a lab and proven to reduce 300 parts per billion (ppb) pentavalent arsenic to below 10 ppb, the
USEPA standard for safe drinking water.
RO systems are not as effective at reducing trivalent arsenic from water. These models will not convert
trivalent arsenic to pentavalent arsenic. If you have free chlorine residual in contact with your water
supply for at least one minute any trivalent arsenic will be converted to pentavalent arsenic and reduced by
this RO. Other water treatment chemicals such as ozone, and potassium permanganate will also change
trivalent arsenic to pentavalent arsenic. A combined chlorine residual (also called chloramine) may not
convert all the trivalent arsenic. If you get your water from a public water utility, contact the utility to find
out if free chlorine or combined chlorine is used in the water system.
Maintenance
It is strongly recommended that you follow the maintenance instructions and have your water tested
periodically to make sure the system is performing properly. See replacement element information above
for recommendations on maintaining your Reverse Osmosis drinking water treatment system.
