My wonderful built in vac was driving my nice neighbor nuts when we cleaned the house. So this unit has been great. I rerouted the exhaust from the outside to directly under the house . The filter keeps it clean down there, and it reduces the noises by about half at the outlet.. but now, since it is under the house it?s really quieter outside. Happy Neighbors.
