Question Answer Comments
Will low pH or acid water affect the Multi-
Pure filter? No. Mineral components expressed as acidity
and alkalinity determine pH. Neutrality is 7;
below 7 is acidity; above 7 is alkalinity.
Does deionized water or soft water have
any affect on Multi-Pure water? No. N/A
Can the Multi-Pure System be connected to
an automatic ice-maker? The below sink models can be connected to
both your sink and refrigerator, to any type of
water dispenser or ice-maker. You can use
the same unit installed under your sink to
also filter the water at your refrigerator. To connect a single Drinking Water System
to both your sink and refrigerator, request an
"ice-maker tee" on the order form.
Can the Multi-Pure System be used during
an emergency or when the water is turned
off? Yes, you can hand pump or siphon water
through the Multi-Pure System during an
emergency. CAUTION -- the Multi-Pure
System is not intended to be used where the
water is microbiologically unsafe or with
water of unknown quality without adequate
disinfection before or after the unit. If water source is questionably
contaminated, it should be disinfected prior
to use. Add ¼ tsp of household bleach per
gallon of water; the Multi-Pure System will
remove this solution from the water. Hand
pump kits are available from Multi-Pure.
What causes "white" particles to appear in
Multi-Pure water when it is frozen or
boiled? The natural minerals in the Multi-Pure water
solidify when the water is frozen, and those
minerals appear as white flakes or specks
when the ice melts. Natural minerals are beneficial to good
health and their existence in drinking water
(in normal quantities) should not cause any
alarm. Minerals can be removed by Reverse
Osmosis technology, which is also available
from Multi-Pure on request.
Why does the Multi-Pure System reduce
Volatile Organic Chemicals, but not natural
minerals? Minerals are totally dissolved in solution and
do not have an actual physical size; thus, the
minerals pass through the filter unchanged. The materials used in Multi-Pure Drinking
Water Systems are specially selected for
their ability to react with the chemicals in the
water, but not with natural minerals that are
beneficial to good health.
Should sediment be removed with a
standard filter first? In areas with excessive sedimentation,
prefiltration will help extend the operational
efficiency of the Multi-Pure cartridge;
however, in most areas this is not
necessary. The Multi-Pure System contains a triple filter.
The outside material is a prefilter that helps
protect the solid carbon block surface from
prematurely clogging with large sediment.
Why is the compressed activated carbon
block filtration system more efficient than
activated carbon (loose granular)
systems? Multi-Pure's solid carbon block filters are
compacted into a dense structure causing
every molecule of water to be forced through
microscopic pores of carbon, effectively
reducing a wide range of contaminants of
health concern (see Section 3), as well as
adsorbing tastes and odors and removing
particulate matter removed by typical
activated carbon filters. The Water Quality Association reports that
"an activated carbon filter can reduce
organics and solid particles, as well as
offensive tastes and odors." Only precoat
and solid carbon block filters are engineered
to provide 0.5 micron mechanical filtration.
What is the difference between a "water
softener" and the Multi-Pure Drinking
Water System? Softeners are not used to treat drinking
water; they are used only to change the water
hardness. Softeners put sodium into the
water in exchange for magnesium or
calcium ions. Multi-Pure Drinking Water
Systems do not remove dissolved minerals,
so, the pH is not changed. Natural minerals
most often found in water are considered to
be essential to good health. Soft water is good for bathing and laundering
and may extend the life of hot water heaters
and boilers. However, soft water should not
be used for watering plants or lawns. It is
recommended that you bypass a water
softener when installing your Multi-Pure
Drinking Water System.
Can the Multi-Pure System be used on
untreated water? If water source is questionable, it should be
disinfected prior to use. Add ¼ tsp of
household bleach per gallon of water; the
Multi-Pure System will remove this solution
from the water. Consult your nearest public
water utility for assistance or guidelines on
proper treatment of untreated water. Multi-Pure Systems are designed to be used
on treated water systems; they are not
intended to be used where the water is
microbiologically unsafe or with water of
unknown quality without adequate
disinfection before or after the unit. Systems
certified for cyst reduction may be be used
on disinfected waters that may contain
filterable cysts.
