This filter set is for the Jupiter Classic Athena water ionizer. It consists of two filters: 1) is a very good activated carbon & sediment filter, and 2) is a silver-impregnated activated carbon and biostone filter. Biostone is another name for Tourmaline, which is known to make water passing through it more bio-available to our cells. With these two filters in place you can expect that over 90 of the water's contaminants and up to 85% of Fluoride in the water will be removed.
Change Biostone Carbon filters at least once yearly and Sediment filters twice a year.
