2. Important Safety Instructions
To reduce the risk of fire, electric shock, or injury, always follow these basic precautions:
- Read all instructions before using the humidifier.
- Always place the humidifier on a firm, flat, waterproof surface at least 12 inches (30 cm) away from walls and appliances.
- Do not place the humidifier near heat sources such as stoves, radiators, or direct sunlight.
- Unplug the humidifier from the power outlet before filling, cleaning, or moving it.
- Do not immerse the power cord, plug, or the main humidification unit in water or other liquids.
- Prevent water from entering the power hole and the internal chip. The humidification unit contains sensitive electronic components; do not put it upside down or soak it in water to clean it.
- Ensure the connection between the humidification unit and the water bucket is secure using the elastic buckle to prevent the unit from floating.
- Keep out of reach of children and pets.
- Use only clean, cool tap water. Distilled water is recommended to minimize mineral buildup.
- Do not add essential oils directly into the water tank; use the designated essential oil tray.

6. Maintenance and Cleaning
Regular cleaning is essential for optimal performance and hygiene. Always unplug the humidifier before cleaning.

Thorough Cleaning (Weekly or as needed)
The innovative design allows for thorough cleaning, especially important if using essential oils.
- Disassemble: Open the buckles on both sides of the humidification unit. Separate the humidification unit from its cover.
- Clean Components: All parts that come into contact with water or mist can be easily cleaned. Use a soft brush or cloth and a mild descaling solution (e.g., white vinegar) to remove mineral buildup from the transducer and other surfaces. Rinse thoroughly with clean water.
- Reassemble: Ensure all parts are dry before reassembling. Secure the humidification unit and its cover, ensuring the buckles click into place.
