The Classic Athena UltraWater & Fluoride Filters-Set consists of: 1 UltraWater Filter for Jupiter Water Ionizers and 2 Fluoride Shield filters. This set enables the absolute filtration of Fluoride, chlorine, chloramines, pharmaceuticals, heavy metals, pesticides, and a plethora of other contaminants you don't want in your water, but allows the good, healthy minerals to pass through. It is proven that our bodies need water that has good minerals dissolved in it. Note: Fluoride removal is up to 99.99%. If you're looking for the absolute best filtration, this is it!

Change UltraWater filters at least once yearly (or every 1000 gal.) and Fluoride Shield filters twice a year (or every 500 gal.)'
Note: The AlkaViva water experts state that the Fluoride Shield filter is not for sediment and a separate sediment filter may be required to prevent clogging of the very fine Ultrawater filters. If you have a water sediment problem you are probably better off getting the external Fluoride Shield and then inside the ionizer use the standard UltraWater filter set (which has a sediment filter as part of the set).
