Maintenance
Regular cleaning is essential for optimal performance and longevity of your diffuser.
- Daily Cleaning: After each use, empty any remaining water from the tank. Wipe the inside of the tank with a soft, damp cloth.
- Weekly Cleaning: For a more thorough cleaning, especially if using essential oils regularly, gently clean the ultrasonic plate with a cotton swab dipped in white vinegar. Rinse the tank with clean water, ensuring no water enters the air outlet.
- Oil Residue: If essential oils are added regularly and the humidifier is left unused for a long time, leftover oil may harden and cause the lid to stick. You can gently pry it open with a tool if needed.
- Storage: When not in use for an extended period, clean and dry the diffuser thoroughly before storing it in a cool, dry place.
