When the Karl big humidifier gets going, rooms of up to 150 m2 are humidified in no time, saving electricity. In large offices, the evaporator ensures healthy and pleasant humidity just as in a spacious bedroom or living room. In auto mode, Karl big automatically adjusts the humidification output to achieve the desired humidity of 40-55 %. The efficient evaporator impresses with its 11-litre water reservoir, which can be filled through a hinged opening on the top. And when the water tank is empty, Karl big switches off automatically. The WiFi equipment ensures that all functions can be controlled via a smartphone app and the humidity can be monitored from anywhere at any time. And for an undisturbed sleep, the LED function lights from the Karl big humidifier can be dimmed or switched off completely.
