KDF Water Filters

What is KDF?

Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc formulation. KDF uses a basic chemical process which is known as redox (oxidation/reduction). This chemical process removes iron, chlorine, mercury, lead, and hydrogen sulfide from water supplies and is used in pretreatment, primary treatment, and wastewater applications. KDF media supplement or replace existing technologies to dramatically extend system life, reduce heavy metals, microorganisms, scale, lower total cost, and decrease maintenance.

How does KDF work?

The KDF redox process works by exchanging electrons with contaminants which converts many contaminants into harmless components. Redox involves the transfer of electrons between two molecules which changes these molecules into different elements. The loss of electrons can change contaminants into less harmful, or even harmless, elements. Some harmful contaminants are electrochemically bound to the KDF media while others are converted to harmless components, such as chlorine to chloride.

Are KDF Filter Media recyclable?

Yes! Patented KDF process media feature Green Filtration. KDF process media contain no chemical additives and are 100 percent recyclable. Many places such as hospitals, municipal water treatment facilities, restaurants, and homes rely on KDF process media to safely and effectively reduce or remove chlorine, hydrogen sulfide, iron, heavy metals, and bacteria from their water.

What is KDF-55?

KDF-55 Media Reduces: Chlorine Taste & Odor, Heavy Metal Removal and Bacteria
A KDF-55 filter media is made of finely granulated zinc and copper alloys. When water passes through the media, the combination of these two alloys in the media produces the chemical reaction of redox (Oxidation-Reduction). Redox involves the transfer of electrons between two molecules. Atoms with a positive charge are attracted to the negative charge of the zinc, while atoms with a negative charge are attracted to the positive charge of the copper. In the KDF process, electrons are taken from harmful contaminants, like chlorine, which is then changed into the harmless, water-soluble chemical chloride when it loses an electron. KDF55 media uses the redox method to remove chlorine, chlorinated hydrocarbons, and metals like lead, arsenic, aluminum, mercury, and cadmium from water.

What is KDF-85?

KDF-85 Media Reduces: Iron and Hydrogen Sulfide
KDF 85 is efficient at removing iron and hydrogen sulfide. KDF-85 also controls scale, bacteria and algae. KDF 85 may be used alone or may be used to protect existing water filtration/purification technologies. Like KDF55 media, KDF85 uses the redox method to remove chlorine, chlorinated hydrocarbons, hydrogen sulfide, iron, and metals like lead, arsenic, aluminum, mercury, and cadmium from water.

What are the benefits of KDF?

KDF 55 and KDF 85 Process Media remove up to 99% of water-soluble lead, nickel, mercury, chromium, and other dissolved metals. Also, KDF Process Media controls the buildup of bacteria, fungi, algae, and scale. They can be used in GAC beds, ion exchange resins, carbon block filters, and inline carbon filters. KDF Media eliminates the need for harmful or costly chemical treatments.

How Does KDF Control Microorganisms?

There are two ways in which KDF process media control microorganisms. The first way is a by-product of redox; an electrolytic field in which most microorganisms can't survive is set up by the exchange of electrons. The second way interferes with the microorganisms' ability to function, by the process of forming hydroxyl radicals and peroxides from some of the water molecules.

Why are KDF Filters Used with Carbon Filters?

KDF filters are often used with an activated carbon filter because they help reduce chlorine build-up which will prolong the life and increase the effectiveness of carbon filters. KDF Filters also supplement the activated carbon filters by removing heavy metals, which carbon-based filters do not remove very effectively.

Why is KDF Used in Shower Water Filters?
KDF is effective at higher operating temperatures and flow rates so it is used in home showerhead filters.

How Long has KDF been Around?
KDF Fluid Treatment, Inc. developed the technology in the mid 1980's and in 1987 was patented. KDF filter media meets EPA and Food and Drug Administration standards for levels of copper and zinc in potable water. KDF is also certified by NSF International to its Standard 61 for drinking water.
