HOW OUR SYSTEM WORKS:

MECHANICAL FILTRATION

Mechanical filtration is achieved with 5 large filter beds with 6 different filter media, by 4-micron-rated Anti-Channel Filter Disks, and also 2 additional self- cleaning filter screens. This type of filtration removes suspended particles such as silt, sediment, sand, rust, dirt, and other undissolved matter.
Optional add-on of 0.5-micron Ceramic post filter eliminates the smallest of microorganisms (cysts, Giardia, Cryptosporidium) and unwanted debris from your drinking water, but allowing the life-giving minerals to remain!

The water also passes through a bed of a media made of a special, high-purity alloy blend of two dissimilar metals - copper and zinc. This media, patented in 1987 by KDF Fluid Treatment, Inc.,
is a major advancement in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (redox) principles.

Through this basic chemical process known as redox, (oxidation/reduction), KDF process media works behind the scenes to rid your water of chlorine, lead, mercury, iron and hydrogen sulfide.

Chlorine is instantaneously and almost inexhaustibly oxidized. Tests on our appliance have shown 99.9+% chlorine removal past 20,000 gallons of water while a high quality carbon cartridge of comparable volume drops below 90% effectiveness after only 4,000 gallons.

Iron and hydrogen sulfide are oxidized into insolubable matter and attach to the surface of the media. Heavy metals such as lead, cadmium and aluminum are removed from the water by the electrochemical process. They are attracted to the surface of the media, much like a magnet.

The media also inhibits bacteria, algae, and fungi growth throughout the entire unit (in fact, has been shown to reduce it up to 99%!), eliminating the need for silver commonly used in carbon-only filters (silver is considered a pesticide by the EPA and must be registered with them).
