DI COLOR CHANGING RESIN Deionization 4 LBS BAG (Green or Blue)

Regular price $35.00

DI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero and is the last stage of an RO/DI unit. It is unnecessary to use the expensive proprietary DI cartridges that other RO manufacturers sell. Simply buy a refillable DI cartridge if you don't have one already and fill with DI resin. You'll save money and get the same results.
