Customer Review: Air King 9137
Does not fill perfectly in the window, but is powerful and QUIET on the low setting. On high it starts to sound like a helicopter.
Customer Review: Multi-Use fan
Very quiet fan which can be used to bring in new air, or use as an exhaust fan particularly for smokers. I may buy a couple more just to circulate air in other rooms. Definitely recommend.
