The ion-exchange resin filter softens hard water by removing calcium and magnesium ions. This creates a lime-free mist that is clean and leaves no white residue. No limescale is deposited inside the device either. Additionally, the filter eliminates bacteria, which makes the mist produced by the humidifier even more healthy for you and your child.

Depending on the frequency of use of the humidifier, it is recommended to replace the filter every 4-6 months.
