What is KDF media?

KDF media, or Kinetic Degradation Fluxion, is a specialized filtration material used in water treatment. It consists of high-purity granules of copper and zinc. Due to the redox reaction between these metals, KDF media effectively removes various types of contaminants from water.

In contrast totraditional filters, the KDF media not only filters water but also prevents the growth of bacterial flora inside the system. This is possible due to the bacteriostatic properties of copper and zinc. It is often used in combination with other filter materials, such as activated carbon, which increases the overall effectiveness of the system.

The KDF media is obtained through specialized manufacturing processes that ensure its highpurity. This makes it indispensable in systems filled with activated carbon, where it improves water quality and extends the lifespan of the filter. KDF media are of interest to both residential and industrial users looking for effective water purification methods.

KDF Filter - advantages

Filters with KDF media offer a range of advantages that make them exceptionally effective in water treatment:

It's worth remembering: The KDF media not only filters water but also prevents the growth of bacterial flora within the system.
  • Removal of heavy metals: Effectively eliminates heavy metals such as lead, mercury, or cadmium, allowing for the reduction of heavy metal contamination to a minimal level.
  • Chlorine reduction: Removes chlorine from the water,which not only improves taste but is also beneficial for health.
  • Elimination of organic contaminants: Neutralizes organic contaminants that can negatively affect water quality.
  • Improvement of taste and smell: Significantly improves the smell of water and its taste qualities.
  • Extension of system durability:Helps extend the lifespan of filtration systems by preventing the accumulation of contaminants.
  • Bacteriostatic action: Prevents the growth of bacteria in the filter, which increases hygiene and safety of use.

If you are looking for an effective solution to improve the water quality in your home, the KDF filter may be an excellent choice. It enhances taste, removes contaminants, and is an investmentfor the health of your family.

KDF Filter Media - Applications

KDF filter media has a wide range of applications in various filtration systems. Below we present the most popular ones.

KDF Shower Filter

Are you tired of dry skin and dull hair after bathing? The KDF shower filter is an excellent solution. It removes chlorine and heavy metals from the water,which has a direct impact on the condition of the skin and hair. The human body is sensitive to pollutants in water, which can cause irritations and allergies. Thanks to the KDF filter, bathing becomes more pleasant and healthier.

KDF Softening Filter

Softening filters work great with the KDF medium. Often, the cartridges are filled with these two types of media, creating a synergistic effect. Softening Resinreduces water hardness, and the KDF media eliminates contaminants such as chlorine and heavy metals. As a result, you lower the concentration of heavy metals and improve the overall water quality.

Water softener with KDF media

In high-quality water softeners, KDF media is used as an additional element in the filtration media. In addition to softening water, KDF media removes chlorine and organic contaminants. It also hashas bacteriostatic properties, allowing for the control of bacterial growth in the system. As a result, the water is not only soft but also safe and clean.

KDF Carbon Filter Cartridges

KDF carbon filter cartridges are an excellent alternative to traditional carbon cartridges. They are often used as a replacement for carbon cartridges because the combination of activated carbon with KDF media enhances filtration effectiveness. Such a cartridgeeffectively reduce contaminants, including chlorine, heavy metals, and organic pollutants.
