In summer, our hall is always very cold and damp, airing only makes matters worse, Condensation and perspiration water, just an uncomfortable indoor environment. Through a storm still flooding came about, and it formed stick stains on the walls and the typical musty smell. We ordered this device to simply times to see if it has any benefit. And how! After five hours, the container was full. If allowed to run for approximately 16 hours a day dehumidifier, come loose 8 liters together, incredible. The climate has become totally enjoyable. Other spots have not shown - despite the currently very wet weather. At first we were a little skeptical, because there is a hallway with staircase and one the 'space' so can not ignore, as recommended by the instructions. This part also looks appealing. The sound is a bit strange, a bit like when the dishwasher is running, you get used to it eventually. However, it echoes in the hallway / stairwell anyway a little more than a room. Plastic odor was noticed only in the first two hours, but not strong - and somehow you're already grateful if you no longer noticed the musty smell :). The container can empty itself properly, the unit switches off when the 3 liter are attained. The air is heated a little, does not interfere in the hallway so. Operation is easy. Just unpack, plug it in - and off you go. For this price range class. We are still a buy us for the basement, for prevention. Addendum: True, there are "only" 2 liters, thank you for the comment :); Nevertheless, the device works very, very effective. We have now more than a year; new patches have not been shown; it is regularly used, although not as intense as in the first year. The indoor climate is top - and the first electricity bill at the end of the year has also brought :) nothing remarkable. Excellent. And free water for casting you get also still ...
