This unit, for our guest bedroom, replaced a much smaller one that was extremely quiet. We wanted the exact equivalent and this one came closest, but it was larger in size and capacity. It works quite well, it is easy to empty the reservoir, and has maintained low humidity in that part of the house. The only problem is that it is quite loud, especially when the compressor kicks in. I think it would be hard to sleep with this thing grinding away in the same room!
