Benefits of KDF® Process Media

  • Removes over 95% of chlorine, iron, heavy metals, and hydrogen sulfide on its own.
  • Extends carbon life when combined with granular activated carbon (GAC), lowering replacement frequency.
  • Boosts the performance and lifespan of GAC, RO, and IX systems.
  • Reduces material needs for more compact, cost-effective systems.
  • No chemical additives—100% recyclable, eliminating disposal costs.
  • Effectively controls scale, bacteria, and algae.
  • Replaces toxic silver-impregnated systems.

How KDF® Media Works

KDF®, short for kinetic degradation fluxion, isn’t just a material—it’s a breakthrough process, pioneered by water treatment expert Don Heskett in 1984. Using high-purity copper and zinc, KDF® media creates an electrochemical reaction that targets and eliminates a wide range of contaminants like iron, chlorine, hydrogen sulfide, heavy metals, and bacteria. Through a redox (oxidation-reduction) process, harmful elements are transformed—chlorine becomes harmless, water-soluble chloride and heavy metals like lead and mercury are captured on the media’s surface, effectively purifying the water.

kdf_water_animation of the filtration processPurity Meets Performance with KDF®

KDF®-55 and KDF®-85 Process Media remove up to 99% of water-soluble metals like lead, mercury, and nickel while controlling bacteria, algae, fungi, and scale. Ideal for GAC beds, ion exchange resins, and carbon filters, KDF® media eliminates the need for harmful chemical treatments.

For chlorine reduction, KDF® Process Media creates a chemical reaction in filters by donating two negatively charged electrons to each molecule of chlorine to reduce it to the lower oxidation state of chloride. Chloride is a highly soluble and innocuous molecule that doesn’t possess oxidation properties any longer.

Guaranteed for purity, KDF® media are 100% recyclable and contain no chemical additives. Certified by the EPA as a “pesticidal device,” our media meet strict EPA and FDA standards for potable water.

 

 


 

Frequently Asked Questions About KDF® Process Media


Kymera’s KDF® filtration media (high-purity copper-zinc) use a redox reaction to reduce a wide range of common water contaminants. Depending on the specific KDF® media used and system design, it can help reduce:

  • Free chlorine (commonly cited as 99%+ reduction in properly designed applications)
  • Water-soluble heavy metals such as lead, mercury, and nickel (often cited as up to 99% reduction)
  • Iron and hydrogen sulfide (for media designed for those targets, commonly cited as 90%+ reduction)
  • It can also help control scale and inhibit the growth of microorganisms within the filtration system (supporting cleaner operation and longer filter life).

Yes.  KDF® media is versatile for point-of-entry and broader treatment use cases, including residential water treatment as well as commercial, municipal, and industrial systems. It is often used as a standalone stage or as a complementary stage to protect and extend the life of downstream media (for example, carbon, resins, or membranes), depending on the application.

Replacement timing depends on water quality, usage volume, system sizing, and whether the system is properly maintained (for example, backwashing where applicable). That said, KDF® media is typically described as long-lasting compared with many traditional filter medias, and it is often expected to last for years (commonly cited as up to around 10 years in appropriate operating conditions). Regular maintenance (like backwashing when required) and correct sizing are key to achieving that lifespan.

Compared with traditional media alone (for example, carbon by itself), advanced media like KDF® can offer:

  • Broader contaminant reduction (especially for chlorine and certain heavy metals)
  • Longer media life and reduced maintenance frequency in many systems
  • Protection for downstream components (helping carbon, resins, and membranes perform better and last longer)
  • Reduced scale buildup and improved control of microbial growth inside the system without adding chemical disinfectants
  • A recyclable media option (often positioned as an environmentally friendly choice)
