The filter (or cotton swab) is not completely soaked. The cotton swab in the mini humidifier is used to absorb water. For better performance, we recommend users to completely soak the filter rod before inserting the humidifier and turning it on. 2: If the spring is missing. Check if the spring is still under the filter. the cotton swab will not be able to absorb water effectively, and water mist will not be generated even if the button is pressed. 3: Essential oils or other water treatment chemicals is not good for the humidifier. It is best not to add essential oils in the water tank, which will affect the spraying ability of the humidifier. 4: The filter (or cotton swab) need to replace. After long-term use of the cotton swab will become dirty and hard, causing the humidifier to produce less steam or even stop working; it is recommended to replace the cotton swab every 1 to 3 months, depending on how often you use the humidifier and the type of water used in the water tank. 5: If the USB cable is broken, If broken please replace the USB cable or a new mini humidifier. 6: If the humidifier is broken, or there are some uncertain problems inside the machine.
