The frequency of the necessary decalcification is reduced. The steamer (not included) guarantees healthy humidification, regardless of quality and mineral content of the water.
It is time to replace the Anti-Mineral-Pad when it is entirely calcified and hard throughout. This comes with 12 pads for easy replacement over time. 
Depending on the degree of water hardness from the steam, the pad has to be replaced every 2–4 weeks.
