HydroPower Ultra S Unger resin replacement DIUBS — the consumable for the DIUH1
The DIUBS cartridge is the specific ion-exchange resin replacement for the HydroPower Ultra S (DIUH1). It is the system’s main consumable — when the resin is exhausted, the unit stops producing water with TDS 0 and the cartridge must be replaced to restore cleaning performance.
When should it be replaced?
The digital TDS meter integrated into the Ultra S continuously indicates the quality of the water produced. When the reading exceeds 10 ppm, this indicates that the resin is exhausted and the DIUBS cartridge must be replaced. Do not wait for the TDS to rise much further — cleaning windows with water above 10–15 ppm can start to leave visible marks as it dries.
Exclusively compatible with the HydroPower Ultra S (DIUH1)
The DIUBS is the specific cartridge for the Ultra S — the smallest model in the range, with just 1 cartridge position. It is not compatible with the Ultra L (DIUH2) or the Ultra LC (DIUH3), which use the DIUB3 cartridge. Always check your equipment reference before ordering.
