Mixed-Bed Resin provides ultra-pure de-ionized water. Highest grade, custom-blended Mixed-Bed Colour Changing Resin Removes most ionized impurities
Features: Cation and Anion resins (H+ and OH-) to remove the remaining total dissolved solids (TDS) from membrane-filtered water *Color-Indicating Mixed-Bed resin provides approximate remaining capacity without metering. However colour may be exhausted well before the resin needs to be replaced. We strongly suggest using an in-line TDS meter with all resins to maximize use of resin and water purity.
