Setup
Initial Preparation (First Use)
Before using the humidifier for the first time, it is crucial to properly prepare the cotton swabs to ensure optimal mist output. Failure to do so may result in no mist or weak mist.
- Turn the humidifier counter-clockwise to open the top section.
- Carefully remove the cotton sticks. Be cautious not to lose the small springs located at the bottom of each cotton stick. These springs are essential for proper function.
- Place the cotton sticks in water and soak them completely for at least 30 minutes. Ensure they are thoroughly saturated.
- Reinsert the wet cotton sticks, ensuring the springs are in place and the sticks are aligned with the holes.
- Add water to the humidifier tank.
- Close the humidifier by turning the top section clockwise until secure.
- If misting is weak, gently shake the humidifier back and forth to help the cotton swabs absorb water fully.

Filling the Water Tank
To fill the humidifier with water:
- Twist the top section of the humidifier counter-clockwise to separate it from the water tank.
- Pour clean tap water into the transparent water tank. Do not add water beyond the "MAX" mark to prevent overflow.
- Reattach the top section by aligning it and twisting clockwise until it is securely closed.

Maintenance
Cleaning
Regular cleaning helps maintain the humidifier's performance and extends its lifespan:
