The humidifier offers adjustable mist levels. Rotate the control knob to select your desired mist output, from low (approx. 300ml/h) to high (approx. 350ml/h). The digital display may show the current setting.
3. Night Light Function
The humidifier features a 7-color LED night light. Press the dedicated light button (if available, or cycle through modes via the control panel) to activate or change the light mode. There are 8 lighting modes to choose from, including a fixed color or a cycling mode.

The humidifier includes optional timers for automatic shut-off. Consult the control panel or specific buttons to set the desired operating duration (e.g., 2H, 4H, 8H, 12H).
6. Aroma Diffuser
Locate the aroma box, typically a small tray on the side or back of the base. Add a few drops of essential oil onto the aroma pad (not directly into the water tank). The mist will carry the fragrance into the air.
7. Automatic Shut-off
The humidifier will automatically turn off when the water level is too low or the water tank is removed, indicated by a red light or an icon on the display. Refill the tank to resume operation.
Maintenance and Cleaning
Regular cleaning is crucial for optimal performance and hygiene. Always unplug the humidifier before cleaning.
Daily Maintenance
- Empty any remaining water from the tank and base.
- Wipe the tank and base dry with a clean cloth.

Weekly Cleaning (Descaling)

- Unplug the humidifier and empty all water.
- Pour 1 cup (240ml) of white vinegar into the water tank and base.
- Let it soak for 30 minutes.
- Use the provided cleaning brush to gently scrub the inside of the tank, the nebulizer, and the base.
- Rinse all components thoroughly with clean water until the smell of vinegar is gone.
