The Lasko twin window fan will keep you cool both day and night. It fits most windows (double-hung, casement or sliding) from 22 inches to 32 inches. The expandable panels of this fully assembled unit provide a custom fit for your window space. The fan can be positioned for intake or exhaust and the slim profile ensures that the outdoors is still within view.
