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
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.
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
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.
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.

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.
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).*
