Have the unit now in the basement for about a month in operation. Background was, that's my son drafted there permanently and just we have in the summer to do it so with partly clear to high humidity. The room is 25 square meters and we have the dehumidifier placed directly at the front door - this is such a great Dehydrator he keeps us the entire basement, including laundry dry. It is also clear that, by the very strong fan, even at the smaller stage running, it is still so loud that you can not sleep here Night stays from the part and during the day he goes then. Within half an hour to turn it again to below 60% RH - so he has enough capacity. The integrated heater (intended for the winter) we have not yet in function, but I'm sure at the fan output will also have its effect. Even so is the dehumidification heat already so developed that the living room is pleasantly warm. Bin the part fully satisfied only at a point rattles the case I could remedy with a screw. Can I recommend.
