.33 Cubic Foot of KDF55 Filtration media – Oxidation / Reduction Anti-microbial Media – 57 lb. Pail


SKU: KDF55-PAIL-57# Category:


Unlock advanced water purification with KDF 55 filtration media, meticulously engineered to reduce contaminants through an innovative oxidation/reduction (redox) process. This high-purity copper-zinc formulation facilitates electron exchange with pollutants, transforming them into harmless components. Chlorine converts into water-soluble chloride, soluble ferrous cations into insoluble ferric hydroxide, and hydrogen sulfide into insoluble copper sulfide, effortlessly eliminated through periodic backwash.

Experience the dual-action microbial control mechanism of KDF 55: the redox reaction creates an electrolytic field hostile to most microorganisms, while hydroxyl radicals and peroxides disrupt their vital functions.


  • Enhances water treatment performance, complementing or replacing existing filtration methods.
  • Removes over 95% of chlorine, iron, heavy metals, and hydrogen sulfide when used alone.
  • Extends the lifespan of Granular Activated Carbon (GAC) when combined.
  • Safeguards reverse osmosis and ion exchange systems, preserving costly membranes and resins.
  • Compact and cost-effective design compared to other technologies, with reduced material requirements.
  • Long-lasting and recyclable, eliminating disposal costs and environmental hazards.
  • Effective against bacteria and microorganisms, disrupting electron transport and causing cellular damage.
