Capacity in m³ x °dH

The capacity depends on your water hardness and water consumption. You can determine the capacity using our capacity calculator or use this rule of thumb:

Water hardness Rule of thumb
Medium-hard water (8–14 °dH) Number of people x 7.5
Hard water (14–21 °dH) Number of people x 10
Very hard water (over 21 °dH) Number of people x 12.5

Example (4 people with water hardness 20): 4 x 10 = 40

A backwash filter should generally be present in every installation. This filters sediments and solids from the drinking water. If you don't have a pre-filter yet, please order one at the same time.

This water treatment system works with the ion exchange process. This means that salt is required to operate. How much salt the system needs depends on the water consumption and water hardness. You can calculate your salt consumption using our online calculator.
