This internal mineral filter may be installed directly inside all Aqua Ionizer Pro® Aqua-Ionizer Deluxe machines and replaces the standard activated carbon filter. Filter media is made of natural corallite coconut shell and activated carbon. This filter is a popular addition for well water, and reverse osmosis customers as it improves total dissolved solids (TDS) in source water and brings the pH levels of source water up to minimum standards prior to being treated by an ionizer machine. Will void your warranty if used on city water.
