Output and room size
Compare stated output (gallons per day) with the room size you need to cover.
Mist type
Ultrasonic models can produce white dust with hard water; evaporative models use wicks that need replacing.
Cleaning
Wide tank openings make the regular cleaning that humidifiers need much easier.
