Highly effective - Remove 99% residual chlorine and keep stable removal performance with 50% longer lifetime than other competitions. The unique combination of nano deoxidization media & carbon fiber creates an electro-chemical reaction. During this reaction, electrons are transferred between molecules and new elements are created. Some harmful contaminants are changed into harmless components. Free chlorine, for instance, is changed into begin water soluble chloride, which is then carried harmlessly through the water supply. Similarly, some heavy metals such as copper, lead, mercury and others react to plate out onto the medium's surface, thus being effectively removed from water supply.
