I have been using the Dehumidifier in my basement. During the summer, the humidity there is more than during the winter but there is humidity there all the time. 
This unit is quiet. It makes a sort of hum you would expect but no loud or high pitched noises at all. It is the quietest dehumidifier I have ever owned. During the summer, I have it above a basin and I have it drain by hose into that drain. Now it is located on the opposite side of the basement and I drain the container. I have found that draining the container is easy. It does get heavy filled with water, so I try to drain it when it is just over half filled. [This review was collected as part of a promotion.]
