Use this nonpressure cartridge system for polishing pretreated water or single-stage deionization
of tap water. Deionizer monitor indicates when it is time to change cartridges. When the monitor
drops below the acceptable minimum purity, or when it registers in the 0.05 to 0.025 MΩ range, the cartridge should be replaced. Monitor shows resistivity of effluent from 25 to 18 MΩ-cm.

Disposable cartridges (sold separately) are easily replaced by turning a thumbscrew.

Deionizer mounts on benchtop or wall.
