      Emily WrightSep 8, 2025
      If the mist from your Levoit Humidifier is not warm after pressing the warm mist button, allow the humidifier to heat up for about 15 minutes. You may also need to clean the heating element.

    Why is the humidity level not changing with my Levoit Humidifier?

      Nicole McbrideSep 10, 2025
      If the humidity level isn't changing in your room when using the Levoit Humidifier, try using a higher mist level setting. Keep in mind that depending on your environment, it may take longer to humidify the air. If the room is larger than 40–70 m² / 430–753 ft², the humidifier will not be as effective.

      If the essential oil in your Levoit Humidifier has little to no smell, add more essential oil. For best results, use pure essential oil.

      Briana SolisSep 14, 2025
      If the mist is warm on the cool mist setting of your Levoit Humidifier, the heating element may still be warm after being used for warm mist. Allow the heating element to cool for at least 30 minutes.

    Why does my Levoit LUH-A602S Humidifier display the wrong humidity?
    • C
      Christine KingSep 16, 2025
      If your Levoit Humidifier's display shows an incorrect humidity percentage, move it to a room smaller than 40–70 m² / 430–753 ft². Make sure the nozzles are facing away from the aroma box, and allow the sensor to air dry if moisture has built up inside. Ensure the humidifier is not within 30 cm / 12 inches of a wall or in a corner. Avoid using the humidifier in dusty rooms and avoid using tap water.
