KDF stands for Kinetic Degradation Fluxion. KDF® filter medium is a high-purity formulation of copper-zinc alloy that reduces contaminants such as chlorine, bacteria and heavy metals using a chemical process called redox, or oxidation-reduction.
The unique combination of copper and zinc creates an electro-chemical reaction. And during this redox reaction, free electrons are transferred between molecules and new elements are created, changing harmful contaminants into harmless components.
Chlorine, for instance, a previously harmful substance is changed into harmless, water-soluble chloride, which is then carried through water. Similarly, some heavy metals such as copper, lead, mercury and others, react to plate out onto the medium's surface, thus being effectively removed from the water supply.
The use of KDF-55 results in total elimination of some contaminants and a great reduction of a wide variety of others.
Why use KDF-55 Filter Media?
KDF filter media are generally used in place of, or in combination with, granular activated carbon (GAC) filters, even carbon block or inline filters. It extends the life of these filters/media by protecting the carbon bed against fouling by chlorine, algae, fungi and bacteria. It controls scale, bacteria and algae, even in hot water. KDF can remove up to 99% of water-soluble lead, mercury, nickel, chromium, and other dissolved metals. It can eliminate the need for costly, and sometimes harmful, chemical treatments.
Benefits of KDF-55 Filter Media:
- Significantly extend the life of other media (carbon) in expensive filter cartridges
- Are 100 percent recyclable and contain no chemical additives
- Effectively remove chlorine and heavy metals and control microorganisms
- Require no EPA registration, thus less red tape
KDF is proprietary Process Media of KDF Fluid Treatment, Inc. KDF-55 filter medium's unique redox process is protected by 14 US patents and numerous non-US patents. The medium is certified by NSF to NSF/ANSI Standard 42 – Drinking Water Treatment Units – Aesthetic Effects. This medium is also in compliance with California’s Health and Safety Code Section 166875 (or commonly known as AB1953) and Vermont Act 193.
