KDF Process Media and Why It’s Important for Whole House Water Filters

Today, you’ll probably notice that most water treatment technologies have limitations – despite how good they are. They cost a fortune, they don’t last long and are often difficult to maintain. Not to mention their inability to combat certain disease-causing microorganisms.  

If you truly want to protect your water from dangerous contaminants and pathogens, you should consider adding KDF (Kinetic Degradation Fluxion) process media to your whole house water filtration unit.  

KDF process media improve water treatment performance by safeguarding, and in some cases replacing, your existing filtration/purification technologies. Many manufacturers, hospitals, restaurants, consumers, and others are already using this exceptional water treatment technology to safely reduce or remove harmful components from their water.

To give you the scoop, we’ll cover what KDF process media are, how they work and why they’re important for whole house water filters.

KDF Media

What is KDF process media?

KDF process media are a unique combination of copper and zinc that reduces contaminants in water using an oxidation/reduction (redox) process.

How do KDF process media work?

KDF process media use a redox reaction to remove chlorine, iron, hydrogen sulfide and other harmful compounds from water supplies by exchanging them with harmless components. They also remove other heavy metals such as nickel, mercury, and copper by simply bonding to the KDF media.

Moreover, KDF process media have a mild effect that helps kill dangerous micro-organisms (bacteria, fungi, algae, etc.) and may prevent the buildup of limescale in your plumbing and appliances.

KDF process media control microorganisms in two ways:

  1. An electrolytic field forms during the exchange of electrons in the redox reaction, which destroys most microorganisms.
  2. After catalyzing the formation of radicals and peroxides in certain circumstances, the radicals can hinder the microorganisms’ ability to function.  

Now that you know how KDF process media work, let’s look at their importance in whole house water filters.

Why is KDF process media important for whole house water filters?

Whole house water filter systems are among the most popular water filtering solutions in the industry. But despite their cost-effectiveness and ability to produce high-quality water, they’re usually not effective enough in some areas of water treatment.

Here’s how KDF filters can fill those gaps:

  • Effectively remove chlorine, iron, hydrogen sulfide and other heavy metals   

KDF media prevent impurities from entering public facilities, homes, and businesses. In fact, they’re said to remove free chlorine. Chlorine removal frees up granular activated carbon (GAC) to better remove organic contaminants, which affect water quality.

Because KDF is more efficient at removing chlorine from water, it provides better-tasting water for you and your family as well as a 50-percent reduction in your chlorine-removal costs.

KDF process media also remove iron and hydrogen sulfide by changing soluble iron into insoluble ferric hydroxide and hydrogen sulfide into insoluble copper sulfide. These new byproducts are strained through the filter bed, then periodically removed by backwashing.

Other heavy metals such as lead, copper, and mercury are removed from the water supply by bonding to the KDF media.

For medical labs and other facilities where purified water is essential, KDF media is a must. Whether used alone or in combination with existing water treatment technology, KDF media remove contaminants from feedwater entering hospitals, and from places that discharge to public water treatment systems.

  • Household water treatment

If your home has a whole house water system, KDF media will remove chlorine and other impurities from the water supply at the point-of-entry. Alternatively, chlorine can be eliminated by incorporating KDF media into shower filters, into cartridges at the tap and at other point-of-use applications. As a result, hotels, restaurants, and homes benefit from better tasting water with less odor as well as less wear and dings on clothes, towels, napkins, bedding and other items that are laundered there.

  • Control microorganisms

KDF media control the buildup of bacteria, algae, fungi, and other microorganisms found in GAC beds, carbon filters and other organic based media. By doing that, KDF media significantly extend the life of the carbon without the need for chemical treatment; Thus, reducing costs and protecting the environment.

  • Extends the life and efficiency of carbon-based systems

Basic activated carbon filters do not handle particulate material very well. However, we use the highest quality coconut shell carbon filters, which contain tiny pores that trap and eliminate similarly sized contaminants. KDF process media enhance the performance, extend the life, reduce the maintenance and lower the cost of carbon-based systems.


The chemical-free operation of KDF makes it a great option for water treatment. Its effective metal removal, microbial protection, scale reduction are worthwhile attributes. Our whole house water systems use coconut shell carbon filters, which makes KDF media a superior inclusion.
