Please note that the
Compact Whole House Units are more powerful than the filters that were
used in the tests above
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 click on

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).*
