Regular price $4,095.00 Sale price $2,495.00
The MineralPURE purification system consists of a state-of-the-art microprocessor control box and a scientifically designed set of electrodes composed of copper or copper/silver alloy set slightly apart from one another. Water is passed through a specially designed flow cell chamber that houses the electrodes. The control box works by generating a precise, low-voltage, DC current (at milliamp levels) to the electrodes. Basically, the current causes some of the outermost atoms of the electrodes to lose an electron, thus becoming positive ions. While the water is running through the chamber, many of these ions are swept away before they can reach the other side of the electrodes. As a result, the mineral ions are dispersed into the body of water that is being purified. The greatest benefit of mineral ionization is that the ions remain in the water providing residual protection. They provide long-term, nontoxic purification and prevent recontamination. Unlike most other types of sanitizers, the mineral ions remain in the water until they flocculate, or form masses with algae and bacteria and then become large enough to be removed by the filtering equipment. When the “used” mineral ions are removed, the microprocessor control box is always producing new mineral ions to continuously sanitize the water. 
Money Saving - Your investment is quickly recovered by reducing your chlorine expenses by 50-75% while still following county, state, and country guidelines. Crystal ClearWater - You will be amazed at the clarity of the water even during heavy bather loads. Health & Environmental - Chlorine absorbs through your skin and harms your health and the environment. Reduces complaints of red eyes & chlorine smell. Time-Saving - Less chlorine use may mean less pool and spa maintenance is required. Reduce Corrosion - Pool/spa equipment, vinyl liners, hoses, covers, pool cleaners, and solar equipment will last much longer. 3 or 5-YearWarranty - Your unit comes with a full 3 or 5-year warranty, except for the electrodes, which need to be replaced on occasion. NSF-certified- The National Sanitation Foundation is the world's leading certification agency that tests products to verify they meet public health and safety standards. (All swimming pool units except the SPA-1R are NSF certified.)
