KDF works on the principle of Oxidation-Reduction or Redox potential. Redox media remove dissolved gases such as chlorine, hydrogen sulfide, and methane from water. They can also remove virtually any soluble heavy metal, help prevent mineral hardness scale accumulation, and reduce levels of microorganisms.
