Short answer
Pick a humidifier whose maker rates it for at least the floor area of your room, then set the most you want to spend on the maker's own store. After that, choose by mist type (cool, or warm and cool), technology (ultrasonic or evaporative), whether it holds a humidity level you set, and how long it runs on one tank.
