The William Ultrasonic Humidifier has a 1.5 gallon tank that can fill rooms up to 1,000 sq ft in size, while measuring an apartment friendly 9.1’’W x 12.2’’H x 6.3’’D and weighing a bit over seven pounds. It’s also extremely quiet and relatively eco-friendly thanks to an off-timer and sleep mode, which dims the lights.
The William Ultrasonic Humidifier runs $230.
