Powerful yet quiet! With Karl, a new generation of efficient humidifiers is here. This compact evaporator can humidify large rooms in no time, all while consuming minimal energy. In auto mode, Karl automatically selects the appropriate humidity level to achieve the desired results quickly and efficiently. Before the water runs out, the water tank can be refilled from above through a flap opening while in operation. All functions of the Karl humidifier can be conveniently controlled on the device or via WiFi using a smartphone app – including monitoring the current humidity level. This ensures an optimal indoor climate at home – even when you're away. For an undisturbed sleep, the LED function lights on Karl can be dimmed or completely turned off.
