Product Overview

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.

what chemicals do you still need to use and are they a special type, different from chlorine pool?
Asked by: sdharrold
No additional chemicals are required for the Mineral Pure Swimming Pool Ionizer. You only have to replace the unit's electrode (at a cost of approximately $150) every few years, depending on the size of the swimming pool.

How often would I expect to replace the electrodes?

Asked by: Ron
I have had a version of this system in operation since 1993. I average a new electrode every 3 to 4 years and have a 20,000 gallon pool.

20,000 Gal. Residential Swimming Pool Ionizer is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Amazing clear cool The dumbest thing I ever did was put in a pool. The smartest thing I ever did was put in this system. in Houston Texas with our heat rain pollen and tree leaves, I struggled for two years with algae growth and pool chemistry. All that is behind me now and the pool is always clear and algae free Maintenance is so simple.

Rated 4 out of 5 by from Mineral Pure Model # 204417795 Installed the system 4 weeks ago. My aging salt water systems died on me, and the cost of repair was more than this unit. With that said, this is a short term review. So after 4 weeks my pool looks fantastic! I mean clear as can be. Water quality is great, I have kept one chlorine tablet in the skimmer. last about two weeks. So here are the pro's and con's as I see it. Pro's: Water Great! Cost of Maintence Low Ease of installation, peace of cake, (do need to know basic PVC plimming. Over all unit price very reasonable. Con's Unit still fairly new, Contacts will Fall out when opening eyes under water, Unlike salt water pool., Do need to keep up on water PH, but should do this anyways.
