The beeping sound cannot be turned off completely.
However, there are a few things you can do to minimize its frequency.
- Timer: Utilize the timer feature on the humidifier. By setting a specific amount of time for it to run, it will automatically shut off after that duration, reducing the need for button presses.
- Full Water Levels: Secondly, make sure that the water tank is filled up to (but not above) the MAX line before going to sleep. This will help minimize the need for any refilling during the night and will reduce the frequency of beeping sounds.
