KDF Filters

KDF process media filters contain high-purity, granulated copper and zinc-based alloys, treating water by utilizing an electrochemical reaction based upon the principle of “Redox” (Oxidation-Reduction). During this oxidation reduction reaction, harmful contaminants are changed into harmless components. Zinc and copper are the preferred metals used in the KDF alloy since both are relatively good reducing agents regarding common inorganic contaminants.

Free Chlorine, for instance, is changed into benign, water-soluble chloride, which is harmless and carried through the water supply. In this way chloramines, bacteria, mercury, fungi, mold, algae, iron, hydrogen sulfide, scale and micro organisms are removed as well. 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.

Advantages of KDF Filters:

• KDF Filters remove contaminants from running hot water (unlike carbon filters where hot water can release trapped contaminants into the water stream), which makes them ideal for showering and bathing.

• Effective removal of chlorine, actually changing the free chlorine some people are allergic to into a less active, easier tolerated form of chlorine.

• KDF Filters remove fungi and algae and control bacterial growth inside the filter.

• These water filters remove cadmium, aluminum, hydrogen sulfide, iron, arsenic, lead, cadmium, mercury and other inorganic compounds.

• KDF process media are a better choice than water softeners (deionizers) if the water hardness is within 15 ppg.

Disadvantages of KDF Filters:

• KDF Water Filter Systems do not remove fluoride.

• KDF process media don’t remove organic contaminants and chemicals like disinfection by-products, MTBE, pesticides, or parasitic cysts like giardia and cryptosporidium. Other filtration systems have to be combined with KDF process media in terms of removal of organic contaminants.

• KDF Filter Systems are quite expensive compared to other Water Filtration and Purification Systems.

• KDF Filters are most effective when combined with other filtration technologies (e.g. Granular Activated Carbon Filters) for full spectrum of protection.
