Maintenance
Regular cleaning and maintenance are crucial for the optimal performance and longevity of your humidifier.
Daily Maintenance:
- Empty and rinse the water tank daily.
- Refill with fresh, cool tap water.
Weekly Maintenance:
- Cleaning the Water Tank: Unplug the unit. Remove the top cover and water tank. Clean the inside of the tank with a soft brush or cloth and a mild detergent. Rinse thoroughly to remove any soap residue.
- Cleaning the Ultrasonic Nebulizer: Gently wipe the ultrasonic nebulizer (the small disc at the bottom of the water tank) with a soft cloth to remove any mineral deposits. Do not use abrasive materials.

When not in use for an extended period, clean the humidifier thoroughly, ensure it is completely dry, and store it in a cool, dry place.
