Maintenance
- Cleaning: It is recommended to clean the diffuser after each use to prevent residue buildup and maintain optimal performance. Use a soft cloth and mild detergent.
- Water Type: Use clean tap water. Avoid using filtered or distilled water, as this may affect the diffuser's mist output.
- Handling: Handle the diffuser with care, especially when it contains liquids. Ensure the top cover is securely in place to prevent spills. Avoid tilting or shaking the device excessively when full, as water may enter the internal circuitry.
