This Jupiter Biostone Carbon Filter is for only Jupiter water ionizers. It can trap a wide variety of contaminants while allowing beneficial minerals to pass through. It uses the highest quality NSF-certified filter media available. It is designed to filter out heavy metals and the most common impurities in city water. The "Biostone" (tourmaline) is designed to reduce the surface tension of the water, naturally, prior to ionization in order to stimulate the best possible ionization.
Change filters at least yearly.
