Bulk DI Resin

DI Resin, Bulk & Refill - the Deionization stage is the final stage of your RO/DI system and is what will purify your water down to ZERO TDS. At AquaFX, we use USA-sourced high-quality resin that are packaged fresh in-house. 

Once water is filtered by the RO Membrane, any remaining impurities is absorbed by the DI Resin inside the cartridge. Impurities have either a positive charge or a negative charge. A mixed-bed DI filter contains both cation resin that absorbs positive-charged impurities and anion resin that absorbs negative-charged impurities. 

For systems with multiple DI cartridges, you also have the option to run different resin in different cartridges. This allows you to extend service life by replacing the cartridge that gets used up quicker. 

All AquaFX DI Resin are of the highest quality and are virgin, nuclear-grade resin (NOT recharged / recycled).
