want to ask, is air purifier able to remove those humid in the air? i mean now my room humid until got mold (yellow/white spot) in some corner, and the wall can see the uneven white layer since my wall is in blue paint.

and some paper box in the room also getting worst, like some yellow spot and etc.

or have to use dehumidifier?

by the way i stay in apartment, and my room has enough sunlight every morning.
