Transform your pool or spa into an oasis of mineral spring-like water and save dramatically on your chlorine expenses. Mineral Pure uses safe and natural minerals to help purify your water, thus dramatically reducing the need for costly chlorine. Chlorine is strong bleach and is dangerous. Studies have linked it to cancer. The bottom line is - nobody likes chlorine. There are nine (9) models to handle any size swimming pool up to 600,000 Gal. The technology used by the Mineral Pure system has been around for thousands of years. It was NASA that harnessed what nature already knew and used a similar ionization system aboard the Apollo flights in the 1960s. NASA granted the manufacturer of Mineral Pure a license to commercialize their technology in 1989. The system consists of a micro-processor control box and a set of a scientifically developed electrodes comprised of safe and natural minerals. Mineral ions are released into the water, helping to disinfect the water. Salt generators actually make chlorine and are subject to costly repairs and replacement. This system only requires the replacement of the electrode (approximately $150) and does not require salt. The electrodes will last 1-6 years depending on size of pool and length of season. All Mineral Pure models featured here are NSF certified for use on residential and commercial pools worldwide.
