10" Granular Activated Carbon filters with KDF for removal of heavy metals from water.
Pack of three 10" GAC (Granular Activated Carbon) filters with KDF powder for heavy metal reduction/removal from water.
Activated carbon filters will remove/reduce many volatile organic chemicals (VOC), pesticides & herbicides. The filter will also remove/reduce chlorine, benzene, trihalomethane (THM) compounds, radon, solvents and literally hundreds of man-made chemicals found in municipal water. Some activated carbon filters are moderately effective at removing some, but not all, heavy metals.
Carbon filters are not generally successful at removing dissolved inorganic substance or metals such as hardness or scale-causing substances, antimony, arsenic, asbestos, barium, beryllium, cadmium, chromium, copper, fluoride, mercury, nickel, nitrates/nitrites, selenium, sulfate, thallium, and certain radio nuclides. Removing these contaminants requires either a reverse osmosis water filter system but some can be removed by KDF.
GAC does not remove sediment/particulate material very well, so they are often preceded by a sediment filter. Sediment pre-filters also prolong the activate carbon cartridge life by eliminating gross contaminants that would otherwise clog the activated carbon, thereby reducing the surface area available for absorption. Carbon block filters are generally better then GAC filters at removing sediment.
KDF filter media is presented in tiny granules of copper and zinc alloys to the extent they look like a powder. Using these two alloys in the filter relies on a chemical reaction of redox (oxidation-reduction) that occurs as water passes through the filtration media. Redox process involves the transfer of electrons between two molecules, transforming the molecules into entirely new elements. In the KDF filtration process, electrons move from harmful contaminants like chlorine and microorganisms. The effect caused by the loss of electrons renders the contaminants into much less harmful, or even harmless, chemical elements.
