This dehumidifier perfectly fulfills its function to a room that is 14m2 (with a sizeable height ceiling): the wall of my closet has stopped dripping water, and mildew dried (just have to clean it!) . So I recommend it for its effectiveness. I would add that it is more economical than a charging dehumidifier since it suffices here to empty the bin. It runs on industry (the cord is long enough) and the fan is not very noisy (I can leave it plugged in sleeping without being particularly bothered). I'm happy with my purchase.
