Water Pro ZS03 Filter

The Water Pro ZS03 is a gel strong cation resin cartridge designed to reduce total water hardness.
Temporary hardness comes from calcium and magnesium bicarbonates and can be removed by boiling, while total hardness also includes permanent salts such as sulfates and chlorides, requiring ion exchange treatment.

The ZS03 is ideal for water that will be heated or nebulized, or where complete softening is required. It does not alter the pH, prevents limescale formation, and enhances the taste of hot beverages such as tea and coffee, while protecting equipment from scale deposits.

Intended for already potable water, the cartridge operates vertically only, with a flow rate of 0.7 L/min and an autonomy of 330–110 liters, depending on the initial hardness level.
