The Constant humidity mode of the Xiaomi Smart Evaporative Humidifier will adjust the operating status according to the humidity and change the speed of the environment where the humidifier is located. If the humidity in the room is detected to rise slowly, the humidifier will automatically increase the humidification amount to reach the target humidity as soon as possible. The actual humidification effect is related to factors such as the area of your room, ambient temperature, humidity and ventilation conditions.
If you think the noise is too loud in Constant humidity mode, you can connect the humidifier to the Mi Home/Xiaomi Home APP and update the firmware to the latest version, which will help reduce the maximum noise in Constant humidity mode.
The update method is listed below:
Open the [Mi Home/Xiaomi Home] APP >> select [Xiaomi Smart Evaporative Humidifier] >> tap the three-dot icon at the upper right corner >> [Firmware update]. During the update process, please ensure that the power connection is normal and the network connection is stable.
