All of the Water Filtration Systems  
On This Website Contain the KDF 55

KDF 55 is a patented product a major advancement in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (REDOX) principles, representing a new and unique way of water processing medium which by its natural process of electrochemical oxidation/reduction and adsorption action reduces and/or removes many unwanted contaminants from water.

KDF media consists of a high purity copper-zinc formulation. These substances exchange electrons or bond with chlorine and other metals contained in the water to create harmless substances.

It operates as a multifunctional medium which has superior capabilities of dechlorination and reduction of dissolved heavy metals drinking water. The dechlorination capacity of KDF 55 medium exceeds that of an equal quantity of activated carbon by over ten-fold.

The process used is known as REDOX (oxidation/reduction), KDF works behind the scenes to rid your water of chlorine, lead, mercury, iron and hydrogen sulfide. The REDOX reaction also inhibits the growth of bacteria, algae, and fungi. As an added benefit, KDF also inhibits bacteria growth (fungi, algae and mold) and eliminates the need for silver that is commonly used in carbon-only filters. Silver is considered a pesticide by the EPA and, as such, must be registered with EPA.

KDF is completely safe and meets EPA and FDA standards for levels of zinc and copper in potable water. Copper and zinc are added to the water during the process in very small amounts, about 0.05 mg/l copper and 0.46 mg/l zinc was measured in tests. The EPA 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 and the FDA recommends a daily intake of 15 mg of zinc and 2 mg of copper.

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 (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.
