For some time the dehumidifier in the basement is now in use and it is always amazing how much water is in the air. The operation is very simple. About a rotating wheel, the device is turned on and determines how "strong" it is to dehumidify. For us he is always running on the normal level. After a few hours the tank was full and was emptied. If one then lets the device the same time run over, and significantly less water in the tank, it is clear that he does a good job. Instead of the collecting container, you can also connect a hose and drain water equal to a drain. So it is possible that the device also dehumidifies the air when the vessel would otherwise already full. The device has next to the handle and wheels make it easy to push back and forth. Actually unnecessary, because the unit is not heavy and easy to carry. All in all, been one of the most sensible purchases recently and I highly recommend it to anyone who has problems with moisture in the basement.
