The MineralPURE system consists of a computerized control box and scientifically formulated set of electrodes composed of copper or copper/silver. A low-volage DC charge is sent to the electrodes, releasing mineral ions into the water. They flocculate with algae & bacteria and are then large enough to be removed by the existing filtering equipment. The system is constantly reproducing new ions all the time. The greatest benefit of mineral ionization is that the ions remain in the water providing a residual protection. They provide long-term, nontoxic purification and prevent against recontamination.
