Patented mixture of zinc and copper called KDF-55, plus crystal quartz, converts chlorine into zinc chloride. Zinc is considered to be helpful in alleviating dandruff and is used in anti-dandruff shampoos.
Unlike carbon, KDF stands up to hot water and is very effective in filtering out chlorine, odors and dirt particles. KDF possesses strong material which helps inhibit the growth of bacteria, fungus, algae and mildew. The Premium Shower Filter contains 16 oz. of KDF and 2 oz. of crystal Quartz for enhanced performance and natural water softening.
