  3. Vornado - PORTAL Window Fan with Reversible Exhaust, Weather Resistant Case, White - White - Front_Zoom
    Top comment

    "Fan...The installation of this window fan was absolutely so easy . It’s a durable window fan with great airflow. ...We’ve always wanted one of these portal window fans for when our air is not working which happens a few times a year. "

    Product Description

    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.

  4. Sharper Image - PROFILE Window Fan with Reversible Exhaust, Weather Resistant Case, Black - Black - Front_Zoom

    Product Description

    Maintaining a low profile isn’t easy when you stand out from the crowd. Other window fans like to draw attention to themselves for all the wrong reasons―overly large and clunky, taking away the view that’s supposed to be yours. Profile lays low by staying 6.61 inches in height and seamlessly installs in windows from 26” to 38” wide. 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.

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 and the slim profile ensures that the outdoors is still within view.
