Raise3D Filament Dry Box includes silica gel desiccant to absorb the moisture from the air. If you don't open the Filament Dry Box frequently, the desiccant can keep the humidity of the filaments below 25% within a month. It is recommended to replace the desiccant every month. Or you can put the desiccant into the microwave oven for 3-5 minutes to restore its drying ability. It is not recommended to use other kinds of desiccants.
