This is the best dehumidifier that I have ever owned. Not only is it very energy efficient, but it has the ability to wick away the dangerous moisture an potential mildew in the air in every large room in my house in absolutely no time at all. This thing gets used overtime in the winter in my house. I swear by it to keep our home fresh, and I know that since I have been using it these last couple of winters, it has kept my families colds and flus at bay. It is not too noisy of a unit either, and very easy to move around from room to room. The dehumidifier does not need to run very long, I use it maybe a couple of hours everyday. I also empty it out every day because I love to see just how much moisture from the air it has trapped, it is very satisfying and reassuring to me. I have owned it fro over three years now, and it shows no signs of giving out anytime soon. This one is a keeper.
