21 Inch Window Fan

Vornado creates cutting edge products - so when we set out to create a window fan, we did our research and then rewrote the formula. The result was just over 6" tall, unobtrusive and clever enough to be seamlessly installed in windows from 24” up to 38" wide using an innovative modular block system. Its electronically reversible chamber smoothly brings fresh air in or exhausts stale air out. Rain or shine, the weather-resistant casing doesn’t mind. Either way, you’ll still enjoy the view.

Great ventilation option for my office. Not super warm on the north side of our house, and this has done a great job to circulate fresh air. Anonymous. Sat Oct 03 2026

Good fan!!! Attached the legs in 3 minutes or less, that’s it. I’m currently using it on my deck to circulate the air. It’s pretty powerful and quiet. It’s giving industrial vibes. Oh, maybe in a man-cave, she shed, or garage. Aesthetically, I probably wouldn’t use it inside unless my AC went out. It came with additional screws in case you want to mount it to the wall. Enjoy!.
