Generally no, mold and mildew require it to be damp in the room, if it's damp in the room you do not need a humidifier. Using this properly you should never have an issue with mold or mildew, just don't stick it in a closet and leave it running, though the size of the water tank would really prohibit the amount of moisture anyways.
