Crystal Quest uses a Four Stage Filtration System 

FIRST, water passes through two  one - micron filtration pad, small enough to remove all visible particles as well as GIARDIA, CRYPTOSPORIDIUM  and other microbiological CYSTS.

SECOND, Our systems contain a patented media, KDF®(U.S. Patent 4,642,192), which has been tested to drastically reduce or effectively remove: Chlorine, Lead, Arsenic, Barium, Cadmium, Chromium, Selenium, Mercury, Iron and other metals that may be present in the water.  KDF® is listed under NSF standard 61 (health effects) for water treatment plant applications. THIRD,  The Coconut Shell Granular Activated Carbon is used to improve the taste and odor and to remove: Chlorine, THMs, PCBs and hundreds of other organic contaminants that may be present in the water. The Coconut Shell GAC listed under NSF standard 42.

FOURTH, water flows through another two 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. NO REPLACEMENT CARTRIDGES NEEDED  When the unit needs to be replaced, the flow of water will automatically either stop or slow down greatly.

Compare Crystal Quest to Others

Faucet-Mount and Pitcher Fillers

These systems require filter cartridges. They are to be changed every 100 to 1,000 gallons.

Disadvantages:  Changing the cartridges is expensive, time consuming and they do not allow water to be in contact with carbon long enough for efficient removal of the most harmful substances present.

Distillation

This method works by vaporizing and condensing water. It removes most bacteria, viruses, and chemicals.

Disadvantages:  Removes all trace minerals, some which are necessary for the health system. Using this method also requires electricity, and most models are energy intensive and costly to operate.

Reverse Osmosis

This method uses pressure to force water molecules through a membrane. Systems using this method are effective in removing fluoride, nitrate, pesticides, heavy metals and brackish water problems.

Disadvantages: It is expensive, takes eight to nine gallons of water, and three hours to produce one gallon of treated water.

Ultraviolet Disinfection

This method kills viruses and bacteria, and also can eliminate some organic chemicals by using UV light.

Disadvantages: This is expensive and ineffective in water that is colored or  with high turbidity.

Softening (To "Soften" Water)

This method exchanges sodium for magnesium and calcium, and is effective for removing metals such as magnesia, iron, lead and radium.

Disadvantages: Systems using this method add sodium in the process, which may be harmful to your health. They are not effective for removing unwanted organic chemicals, tastes, and odors. They usually treat the entire home water supply, not just water used for drinking and cooking.
