DI Resin
DI Mixed Bed Resin is used in our refillable cartridges. Demineralisation Resins are used to reduce TDS (polishing the water).

The TDS from a RO unit is not always as low as required so using DI resin will bring the TDS down to almost zero.

Our DI resin is supplied in pharmaceutical grade containers, not a plastic bag sent by other suppliers. This ensures that your DI resin is not contaminated or damaged in transit.
