DI Filters & Resin - 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 and we hand-pack our DI cartridges 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.
AquaFX offers pre-packed cartridges as well as empty refillable cartridges that you can fill with the various DI resins we offer.
