What exactly is kdf in the water purifier filter?
By Zhao from Onlyzone,a manufacturer of water treatment bio ceramic ball filter media in China.
kdf is a high-purity copper-zinc alloy, commonly known as water gold.
KDF is developed and produced by the famous American KDF company, and has passed the certification of authoritative organizations such as the National Sanitation Foundation (NSF) and the Water Quality Association (WQA).
It uses the electrochemical (redox) reaction of copper and zinc in water to effectively Remove residual chlorine in water (removal rate up to 99%), water-soluble heavy metals (lead, mercury, nickel, chromium, etc., removal rate up to 98%), hydrogen sulfide and other toxic and harmful substances, and can effectively inhibit the growth of bacteria.
KDF55 treatment medium meets the requirements of the U.S. Environmental Protection Agency (EPA), Federal Drug Administration (FDA), Water Quality Association (WQA) and National Sanitation Foundation (NSF) on the highest zinc and copper content in drinking water, such as KDF treatment.
The media is capable of removing chlorine up to 10ppm in water and still meets EPA regulations for maximum allowable zinc levels in drinking water. Common KDF filter materials are KDF55 and KDF85, the difference is the ratio of copper and zinc.
