Product Description

The CRYSTAL QUEST® Double Undersink Fluoride Removal Water Filter is dependable and built to last for years. Quick and easy to use, stylish, convenient, and effectively removes Fluoride and hundreds of contaminants from water.


  • 7 Stages of filtration.

    • First, a Fluoride Removal cartridge, containing fine-mesh pre-resin media to reduce fluoride molecules to a less than detectable level (below 0.2 ppm). Also effectively removes arsenic. The capacity is up to 11,000 ppm with effluent levels below 0.2 ppm from 10 ppm feed. Note: high pH and high bicarbonate levels reduce the capacity - above 100 ppm bicarbonate, reduction by 50%; above 200 ppm, reduction by 75%.

    • Then, through a 6-stage cartridge, which removes hundreds of contaminants from water. This cartridge provides 10,000 gallons (1-3 years) of quality safe and pure water.

  • Connects to any kitchen faucet.

  • Easy to use and install on all standard sinks.


  • Dimensions: 10" x 12"
  • Weight: 13 lbs
  • Flow rate: 0.75 to 1 gallon per minute

Seven Stage Water Filtration Process

Double Cartridge Undersink Fluoride Filter
In stage 1, water flows through a FLUORIDE REMOVAL cartridge containing a fine-mesh pre-resin media (CQ-900) to reduce fluoride particles to a less than detectable level (below 0.2 ppm). Also effectively removes arsenic.Click here for more information on CQ-900 Fluoride Removing Media.

In stage 2, water flows through pre and post one - micron filter pads (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other un-dissolved matter.

In stages 3 and 4, water flows through a bed of 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 KDF/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. Click here for test data on the GAC/KDF cartridge.

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? No! 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. Click here for more information on KDF filtration.

In stage 5, water flows through ion exchange resins, reducing heavy metals such as lead, copper, aluminum, and water hardness.

In stage 6, 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 causing bad taste and odors in your drinking water.

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.

In stage 7, water flows through another one-micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or total elimination of a wide variety of contaminants.
