Sharper Image 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 a mere 5.45” tall, cleverly enough to be seamlessly installed in windows up to 38” wide using to an innovative modular block system. In today’s world full of ugly, repetitive window fans, Portal is a window fan that lives up to the Shaper Image vision - to bring products today inspired by Tomorrow’s Tomorrow.
