One of these entry level compact whole house units may be the perfect
solution for your home or apartment. If you have a small family of one
or two people these systems are a very economical solution for all or
most of water filtration needs. When your CRYSTAL
QUEST® Eagle® Compact Whole House Water Filters is connected to
the water main entering your home it will provide you with pristine,
great tasting water through every faucet in your home. You will be able
to drink, cook, make coffee and bathe without the worry of what
contaminants you are ingesting or absorbing. They represents the most
robust whole house water system we have ever seen. They removes hundreds
of contaminants from 80,000 and 160,000 gallons** of water depending on
which system you choose.
Technologies Employed
All three of the CRYSTAL QUEST® Eagle® Compact
Whole House Water Filters incorporates the same filtration
technologies. Each system uses a certain amount of the media which
accounts for the different capacity of each system. A host of the most
advanced filtration methods are used in each system. These whole house
units have been tested to treat 80,000 to 160,000 gallons of tap water.
For more details please note each layer of filter media the water passes
through and the contaminates that they target please read about each of
the following stages below>
Stage 1:
Water flows through a 20" sediment filter cartridge that removes
sediment, silt, sand and dirt. Also extends the life of the water
filters.
Stage 2:
Water flows through one - micron filter pads (1 micron equals 1/25,000th
of an inch), which remove suspended particles such as silt, sediment,
cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other
un-dissolved matter.*
Stage 3: Water flows through granulated activated
carbon (GAC). GAC is universally recognized and widely used as an
effective adsorbent for a wide variety of organic contaminants, such as
chlorine (99.9%), chemicals linked to cancer (THM's, benzine)
pesticides, herbicides, insecticides, volatile organic compounds (VOC's),
PCB's, MTBE's and hundreds of other chemical contaminants that may be
present in water that create bad taste and odors.*
Carbon is extremely porous and provides a
large surface area for contaminants to collect. Carbon-only filters must
also use their capacity for chlorine removal, resulting in a shortened
life. They also may use a bituminous coal carbon, which is good at
removing chlorine, but not as effective at removing chemicals. We use a
high-grade coconut shell carbon that is most effective at removing
chemicals. Coconut shell carbon provides a significantly higher volume
of micro-pores than either coal, wood or lignite based carbon. As a
result, it is more effective than other carbon types in removing
trihalomethanes (THM's) and other chemicals from municipally supplied
water. Since our REDOX media removes the chlorine before it reaches the
carbon, the carbon capacity is not wasted on chlorine and is free to
concentrate more effectively on organic contaminants.
Stage 4: Water
flows through ceramic balls, removes harmful bacteria such as E. Coli,
Fecal coli form, Salmonella, Streptococcus, and cysts (Cryptosporidium,
Giardia) and sediment.
Stage 5 and 6: water flows through a
bed of media made of a special high-purity alloy blend of two dissimilar
metals - copper and zinc (Eagle Redox Alloy® 6500, and Eagle Redox
Alloy® 9500.) Eagle Redox Alloy® is a major advancement in water
treatment technology that works on the electro-chemical and
spontaneous-oxidation-reduction (REDOX) principles. Chlorine is
instantaneously and almost inexhaustibly oxidized. Tests on Eagle Redox
Alloy®/GAC cartridge have shown 99+% chlorine removal past 20,000
gallons of water. In comparison, carbon cartridges of comparable volumes
drop below 90% effectiveness after only 4,000 gallons. Iron and hydrogen
sulfide are oxidized into insoluble matter and attach to the surface of
the media. Heavy metals such as lead, mercury, copper, nickel, chromium,
cadmium, aluminum, and other dissolved metals are removed from the water
by the electrochemical process. They are attracted to the surface of the
media, much like a magnet. The media inhibits bacterial growth
throughout the entire unit. In fact, it has been shown to be reduced up
to 90%, eliminating the need for silver, which is commonly used in
carbon-only filters (silver is considered a pesticide by the EPA and, as
such, must be registered with them). Is copper or zinc added to the
water in any significant amount? On 2.3 ppm chlorinated water, <0.05
mg/l copper and only 0.46 mg/l zinc were measured. The EPA aesthetic
levels are 1.0 mg/l for copper and 5.0 mg/l for zinc. Both zinc and
copper are essential minerals for good health - the FDA recommends a
daily intake of 15 mg of zinc and 2 mg of copper. To learn more details

Stage 7: Water flows through another
one-micron filtration pad for further reduction of undesirable
particles. The end result is a great reduction or the total elimination
of a wide variety of contaminants.
Stage 8: In stage 8, water flows through a
20" solid carbon cartridge for removing volatile organic carbon
compounds (VOC's, insecticides, pesticides and industrial solvents).*
