CRYSTAL QUEST Utilizing the latest technologies in water industry, coupled with over 30 years of manufacturing expertise, we provide you with the most effective, healthy, great-tasting water conveniently at the most affordable price. Our products are attractive, easy to install and use and removes more than 500 contaminants from water. Water travels through multiple stages of filtration:
Stage 1 - Water passes through a one-micron filtration pad (1 micron equals 1/25,000th of an inch {a human hair is about 100 microns in diameter}), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other un dissolved  matter.
Stages 2 and 3 - The water passes through a bed of a media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc KDF-55D and KDF-85D. KDF 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 our cartridge have shown 99+% chlorine removal past 20,000 gallons of water while a carbon cartridge of comparable volume drops below 90% effectiveness after only 4,000 gallons.
 Iron and hydrogen sulfide are oxidized into insoluable matter and attach to the surface of the media. Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved materials 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 bacteria growth throughout the entire unit (in fact, it has been shown to reduce it 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 was measured. The EPA aesthetic levels are 1.0 mg/l for copper and 5.0 mg/l for zinc. And remember that 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. Click here to learn more about KDF
Granulated Activated Carbon (GAC) is universally recognized and widely used as an effective adsorbent for removal of a wide variety of organic contaminants from water, such as chlorine (99.9%), chemicals linked to cancer (THM's, benzine) pesticides, herbicides, insecticides, volatile organic compounds (VOCs),  PCB's, MTBE's and hundreds of other chemical contaminants that may be present, 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 micropores than either coal-, wood- or lignite-based carbon. As a result, it is more effective than other carbon types in removing trihalomethanes (THMs) 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 5 - Water flows through another one-micron filtration pad for further reduction of undesirable particles. The end result is total elimination or great reduction of a wide variety of contaminants.
