The dehumidifier purchased from Amazon is now about one month in operation. He was able to reduce our downstairs befindliches bedroom of about 80 to 50 percent. Now he turns on only relatively infrequently to maintain the right and pleasant relative humidity. By the way, it only needs about 120 watts, so a lot less than in the description. And it is also cheaper than most competitors. Thus, I am completely satisfied. Rudikie from Kefermarkt in Upper Austria
