DEMI5, the brand new portable water softener, is perfect for the cleaning of any type of smooth surface, without the need of drying them after the use. The combined system of active carbon filters and ion exchange resins retains the calcium in the water and avoids the formation of scale on the surfaces that have to be washed. The compact shape and the small dimension of DEMI 5 make it perfect to be easily stored, even on board. No more waste of time for drying, no more spots on the surfaces. You can also use the water produced by DEMI5 to fill any kind of tank. DEMI 5 works without electricity, since it uses the pressure of the water supply network.
