Bulk Deionization Resin (Color Changing)
BRS color-changing mixed-bed DI resin is the final stage of an RO/DI unit, reducing total dissolved solids (TDS) to zero; the beads shift from blue to brown as they exhaust so you can tell when to change the cartridge. Sold in a 1.25 lb single-cartridge refill or a 1.5-gallon (7.5 lb) bulk bag that fills six standard 10-inch refillable cartridges, packed in foil-lined Mylar bags with a 2-year unopened shelf life.
Price: $59.49 USD
