Exhaust Shutter Fan
Key Specs
Capable of moving 294 cubic feet of air per minute, the power of this fan makes it well-suited for areas with serious exhaust needs, like steamy bathrooms, stuffy attics, or even smoky rooms. The four louvres on the rear of the unit remain closed when the fan is not in use, and they also help block debris or insects from getting inside.
While this model gets an average 4.2-star average user rating from more than 1,400 customers, buyers say it’s not particularly easy to mount in a window on its own, so you may need to get creative and build a wooden frame to secure it in place. That said, its light, 4.24-pound weight makes the mounting process a bit easier, though.
Key Specs
It’s not exactly designed to, but this box fan can still technically fit inside a window frame, making it a useful choice for those looking for something with a bit more flexibility than a typical window fan.
Its cord also fits conveniently into the unit itself, which makes this model great for those who prioritize easy storage and don’t want to wrangle cords every time they want some extra airflow. It doesn’t have the bells and whistles of some of the models listed above, but its low price and powerful 1100 RPM motor make it a great option that won’t break the bank.
