I was looking for a dehumidifier for my approx 10m² large basement. Since this was a bit too wet with typically 75% humidity. Unfortunately, no effect was seen by the operation of this device. While there have been collected within 5 days about 2 liters of water but the relative humidity did not change. A compressor based unit, also from Amazon for about 100, does a great job here and keeps the humidity stable at about 60% (with control of ELV set), while it perhaps running 2 hours a day.
