  • COLOR-CHANGING DEIONIZATION RESIN – AquaticLife Mixed-Bed Deionization Filter Cartridge contains positive Cations and negative Anions, each in a different color. DI Resin physically changes colors from Blue to Tan when the media is exhausted.
  • REDUCES TOTAL DISSOLVED SOLIDS TO ZERO – The deionization resin is necessary to reduce Total Dissolved Solids (TDS) to zero in the final stage of an RO/DI system. It uses ion exchange to remove TDS from water.

  • COMPATIBLE WITH MOST RO/DI UNITS – This RO Buddie replacement filter cartridge is compatible with all AquaticLife RO units and only requires standard ¼” tubing to connect. This deionization water filter can be used with most other reverse osmosis water filter systems and RO/DI units.
