My dryer vent is kinked under the house so I set up this indoor unit for a while until I get a chance to fix it. It's been attached for a week or so now. The main disadvantage is eventually you get tired of smelling drying laundry detergent...at least I have. So far, no dust found in the laundry room or around the house from this, so it works, but you must check the water after every other load at least, evaporates fast!
