Double Replacement Cartridges for the countertop model are dependable and built to last for years. The refills can be quickly installed to provide continuous removal of FLUORIDE and hundreds of contaminants from water.

Water travels through 6 stages of filtration. First, through a 5-stage cartridge, then through a FLUORIDE REMOVAL cartridge. Contains fine-mesh pre-resin media in the second unit. The second cartridge reduces fluorides below 0.5 ppm (parts per million). Capacity is up to 15,000 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%. Also effectively removes arsenic, lead, radon, mercury, copper, nickel, chromium, cadmium, aluminum, and hundreds of other contaminants.

Provides 10,000 gallons (1-3 years)* of quality safe and pure water. At the going rate of 99 cents for a quart of bottled water from a store, this $59.99 cartridge can produce over $40,000 worth of delicious, purified, clear water from your very own home.

RESEARCH BRIEF

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 undissolved 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.

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.

Stage 4 - ABSORPTION: GRANULATED ACTIVATED CARBON 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.
