This unit was installed in a 1000 SF bungalow style home built in 1908. The home had high a humidity issue in the basement. I mounted this unit on a metal cart/rack, plugged it into a standard wall outlet and fed the drain tube into a 5 gallon bucket which I empty by hand for now. I will install a condensate pump later and feed to a utility sink. After installing this unit, humidity levels dropped to 50% RH within about 24 hours. Regarding noise/ sound, I consider this unit to be very quiet. I would describe its sound level as similar to a refrigerator running. So far it has worked great, I hope to get many years of service out of this.
