The Dreo 524 is a 6-liter ultrasonic humidifier built for large rooms, with a claimed run time of up to 60 hours on low mist. Its big tank and supersized output put it in the same class as Levoit and Vicks console humidifiers, but it adds app and voice control that most rivals at this size lack. Owners rate it highly for quiet operation and easy filling. It suits bedrooms, open living areas and anyone tired of refilling a small tank every night.
