This versatile Comfort Zone window fan offers 3-speed control to generate a strong breeze or gently circulate the air in your room. The manually reversible fan can intake fresh air or exhaust stale air, while the 7-inch dual blades efficiently move air to keep you cool and comfortable. The auto-locking accordion expanders allow the fan to fit most windows from 22-1/2" to 33" wide, and the removable bug screen keeps out insects and debris. With a carrying handle for easy portability and removable feet for tabletop use, this energy-efficient window fan blends seamlessly with your home decor.
