that you use the ventilation system of the room simultaneously.

is lit, the product does not
humidify.

keep appropriate humidity, when [ (High)] is on.

→ When the humidifying filter is installed incorrectly, the product will
sound abnormally, and not humidify.
The humidity does not increase.
●Is the room size too large for the product?
● Is the room ventilated or having a carpet on the floor?
→ A carpet floor or some types of ventilation and floor/wall materials
may prevent smooth humidification.
