We are delighted to offer CuZn Water Filtration, a water specialist since 1987. CuZn's is the developer of the patented Filter Foam Power Disk water filtration technology that uses a combination of copper and zinc (patented under the trade name KDF®) in water treatment systems to remove chlorine, iron, lead and other heavy metals, bacteria and other micro-organisms, hydrogen sulfide, and hundreds of other organic and inorganic problem contaminants from the water supply. It also reduces scale and hardness, but retains minerals to balance water.
