      kimberly99Aug 29, 2025
      If you notice dampness or condensation around your Levoit Humidifier, it could be due to high humidity. Try lowering the mist level, turning off the humidifier, or improving the room's ventilation by opening a door or window. Ensure the water tank is correctly placed, and wipe off any excess water when replacing it. Proper airflow is essential, so consider moving the humidifier to a more ventilated space.
