Control Panel & Remote Functions:
- Power: Press to turn the humidifier on or off.
- Mist Level (Max/Min): Adjusts the mist output from low to high (3 speeds).

Maintenance
Regular maintenance ensures optimal performance and longevity of your humidifier.
Cleaning:
- Daily: Empty and rinse the water tank daily.
- Weekly: Clean the water tank and base thoroughly to prevent mineral buildup and mold. Use a soft brush for hard-to-reach areas. The wide top-fill opening facilitates easy access for cleaning.
