is annoying that the water tank after removing leaking heavily, so that drags on the way to bath a water trail behind it. The Befeuchtungsleitung is quite good, I was able to humidify a room with 30 square meters (ceiling height 4m) well, but I am because of construction-related droplet formation (a large part of the atomized water remains long as micro-droplets in the air and does not evaporate immediately) again dissuaded and on conventional evaporator switched. People with sensitive bronchi (like me) should probably stay away from US atomizers. Anyway heard my cough immediately after I swapped the device with an evaporator.
