I was very impressed with this model. I didn’t realize how much moisture was in my basement until I starting using it. Now if your basement is like mine after about three days you will have to empty it unless you have it drain which I am in the process of doing so I don’t have to manually do it myself but nonetheless it really isn’t a big deal. I immediately smelt the difference after a few hours and after a day or so constantly running it was great. Also easy to clean as well and maintain it.
