Color-Changing Deionization Resin – AKM mixed-bed DI resin changes from purple to yellow as it exhausts, making it easy to know when replacement is needed. Resin lifespan varies depending on local water quality.
Pre-Filled 10" × 2.5" Cartridge – Our color-changing mixed-bed resin is pre-packed in a standard cartridge, effectively removing Total Dissolved Solids (TDS). Each cartridge can typically remove about 1800–2000 TDS before full replacement is required.
Standard Replacement Size – Compatible with most household RO/DI water systems, this replacement filter fits the common 10" × 2.5" size.
Easy Resin Replacement – Simply unscrew the top cap to pour out the used resin. Refillable with bulk resin to reduce replacement costs.
