Keep an area up to 350 sq. ft. moist and comfortable with this Honeywell HUL535B ultrasonic humidifier, which features variable settings and a multidirectional mist nozzle to deliver soothing, visible cool mist.
The only downfall is that the humidifier doesn't turn off when it's out of water, but at the same time staying in while empty doesn't seem to do any harm to the equipment.
