KDF® (redox method)

KDF (redox method)  is a patented copper and zinc alloy that has become synonymous with the redox method (short for reduction-oxidation).  This media produces an electro-chemical reaction causing molecules to transfer electrons and produce new elements.  Chlorine comes in contact with the zinc and is converted to zinc chloride which has none of the oxidizing effects of chlorine.  On water supplies with a high mineral content, it may also reduce some heavy metals like copper and lead.  This is a powerful dechlorinator, particularly when used on hot water, making this a preferred media for shower and bath filters.

Benefits: Large capacity for the removal of chlorine; is used on both hot and cold water but is most effective on hot water.

Limitations:  Very heavy, making it difficult to back wash in large filters;  price can vary substantially depending on the market price for copper and zinc

Used in combination with activated carbon.
