However, I noticed very quickly that it is apparent only in the maximum extreme Superentfeuchtungsangabe need (at times to call the technical term) act in this specification, which probably reached the unit only in a sauna with infusion. But since you want to dehumidify air in rare active sauna rooms, you can correct this information first down.
Real, at the highest power level, the unit brought in one night just over 3 liters, so in a basement room, which is no longer wet, but in the corners visible still wet bar. And I found the service quite acceptable.
So if the same goal as I was, so to get a basement room, a gazebo, or about a newly renovated room dry, which makes this device everything right. The important thing is that you do not let it run in automatic mode, because it will bring to nothing from the air. Only the maximum level (mode "Dry Clothes") brings a real Austrockungseffekt. The damp corners in the basement were gone within a few days. Since this is a Dehumidifiers should be clear that you do not get around the target area of drying to strong heating. The device can indeed only draw moisture from the air when this is also in it, and that's best done by heat.
We now use the device as a "tumble": Just hang laundry, put device in front and put it on highest level, and even in spite of "the basement drying" the clothes dry in less than two hours.
Conclusion: A really good device, which features performance that you would not expect at this price. It's worth every penny. That, of course, a certain noise level is produced at the highest level, is not by design to prevent. However, a normal hair dryer or a vacuum cleaner is much louder.
