After the renovation of the sewerage system in our street, we are experiencing a high groundwater level. Our basement (20m² / 40m³) is already a bit older and moisture/water sometimes comes through the joints in the floor. The major problem with our basement, however, is that there are insufficient ventilation options. Result: floor does not dry well, mold formation, musty air, ... that could not be removed. Since we use our basement as storage space, this is not very convenient, because all the stuff in it also gets damaged. At the end of August 2024, we therefore purchased this dehumidifier. What made us decide to buy this dehumidifier is the capacity (can dehumidify larger spaces than our basement), the noise level, the ability to purify air, lesser reviews about a competing brand and mainly the pump function (so that we do not have to continuously empty the reservoir, but the water can be pumped directly outside the basement). The app function was a nice extra but not necessary for us (although I have to say that it is addictive to see what the humidity level is, and you can also easily operate the device via the app). When unpacking the device, all accessories were included, including a drain hose (which is at least 5 meters long, probably longer). We laid this on the ground floor (estimated: 2.5 meters higher), the device has no problems pumping up to this height. The manual was fairly concise but sufficient for us. Upon installation, our basement turned out to have a humidity of about 80%. The device was used 24/7 for the first few days, which also went without any problems. It was soon noticeable that the room became less humid, and the smell also improved. However, the device remained at around 60% humidity for about two weeks. We thought this was a shame because 60% is actually the maximum healthy humidity in a home, but we decided to wait a little longer because the device continued to pump away water. A week passed, and we gradually saw the humidity drop further. After asking around, it turns out that walls and objects can absorb quite a bit of moisture, which explains why the device remained at the same percentage. After about a month of use, we notice that the device is around 40% humidity. Ideal, because this is the minimum (healthy) humidity level in a home. This is also what we had set the device to. In short: we are very satisfied with our choice and the device. Dehumidifying takes a long time (this is the case with all dehumidifiers), but patience is rewarded. We definitely recommend the device. If we ever need a dehumidifier again, it will be this one!

Works well. Protip: when you get it, first remove the foil from the filter. Otherwise it will hardly draw any moisture ;)

The dehumidifier is in the hall. Unfortunately, it goes on full power every hour and a half to defrost. That makes so much noise that I don't find it useful for in the house.
