The frequency of cleaning the water tank of the dehumidifier is generally determined by the capacity of the tank and dehumidifying performance. The temperature and humidity of the actual operating environment also have an impact on it. For example: A dehumidifier with a daily dehumidification of 13 liters is recommended to clean the tank every 5-6 hours during the normal wet season in Hong Kong (relative humidity above 80%). If the weather or operating environment is relatively humid, it is recommended to use the included water hose to perform continuous drainage.
