The water descaling filter extends the life of the humidifier. Filter suitable for models CR7973w and CR7973b The filter can be washed from the outside under running water from time to time. The filter replacement time depends on the local water hardness. It is recommended to replace every 1-2 years.The raw material of filter is Maifan stone, it is a natural silicate mineral. Maifan stone is a composite mineral or medicinal rock that is non-toxic, harmless to organisms, and has certain biological activity. The main chemical composition of Maifan stone is inorganic silicate aluminate, it includes SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, K2O, Na2O, TiO2, P2O5, MnO, etc.
