The water is fully filtered 3-5 times between each float, passing through an intense filtration system for particulate matter and then a UV filter which targets the DNA and RNA of bacteria, viruses, algae and other biological matter. Furthermore, the Epsom salt solution is naturally sanitary; the combination of the high concentrations of Epsom salt and a small amount of disinfectant make it cleaner than a pool and nearly impossible for microorganisms to survive.
