The Best Whole House Fans for Ultimate Air Circulation in 2023

Shoppers who don't have a ton to spend on their whole house fan can still get a lot for their money with this gable ventilator from Cool Attic. This unit installs in a gable vent and pushes hot air out of the home or attic, sucking fresh air in through the open windows. Though one air vent fan only draws 1,300 CFM, installing two units on either end of an attic space will bring in quite a bit of fresh air through open windows—and purchasing two of these fans is still less expensive than buying a single whole house fan from most other manufacturers.

As inexpensive as it is, the Gable Mount Power Attic Ventilator still offers some desirable features. Its direct-drive motor is low maintenance, so users won't have to worry about changing belts. There's also a built-in temperature sensor that can be set to turn the fan on automatically, which ensures the home stays cool when the heat rises.
