I ordered this unit For my small basement about a month ago after a lot of research. It has lived up to all expectations. I used the bucket initially and then switched to a hose attachment so that it drains into my sump pump. The humidity level dropped dramatically within 12 hours and the musty, mildew smell dissipated as well. Cleaning the filter every 2 weeks is simple to do. So far I cannot think of any negatives! Very happy !
