One Cartridge Refill (1.25 lbs.) DI Resin (Color Changing)
This nuclear-grade color-changing DI resin (1.25 lbs) fills one standard 10-inch refillable DI cartridge — the last stage of an RO/DI unit that reduces total dissolved solids to zero — and changes color when exhausted for an easy visual indicator. Vacuum-sealed in foil-lined 4mm Mylar bags to preserve freshness for up to 2 years.
