Why is the Xiaomi Smart Evaporative Humidifier still drying even though the filter element has been dried?

The humidifier will automatically enter Standby mode after the filter element has been dried. If the filter element has been dried but the humidifier is still drying, press the Standby button to enter Standby mode directly.
Note:
1. The humidifier will start drying the filter by default when pressing the Standby button. It can effectively reduce the odor and mold problems of the filter element. Therefore, it is normal that the humidifier still works when you press the Standby button;
2. In High-power mode, the filter drying takes 45 minutes, and in Constant humidity and Sleep modes, the filter drying takes 90 minutes.
