The dehumidifier was no longer equal to 1 hour. Have these sent back immediately. After an hour, a few drops were to be found in the collection container, and that in a room (12m2) with 72% hydrochloric moisture. Actually a very weak performance. The Elro DHi600 would run with me 24 hours, so I get a satisfactory result. Quiet se it is not. Is similar to a Badtlüfter. Even my old refrigerator is quieter. After much googling I found that although more expensive devices consume more power, but does not have to run in continuous operation. Have decided for this variant. Please googling yourself to distinguish, you will not regret it. Since I do not know if I could travel ellen a link here, please googling myself under: Compared: Peltier mini dehumidifier dehumidifier compressor against According to tests hold appliances with Peltier technology is not very long, what experience I had to make. This was my first review ever in Amazon.
