JUDO i-soft plus

I-soft plus model

The fully automatic water softener i-soft plus ensures constant soft water quality without interruption with its stagnation-free operating processes; It detects fluctuating initial hardness with the i-guard sensor technology and automatically compensates for them with the i-matic control, thus delivering the soft water you want around the clock. In addition to the advantages of the i-soft safe devices, the system also offers WLAN and USB connections, a leakage sensor and a particularly intuitive touch display. The i-soft plus can also be controlled via app or Alexa voice command.
