How to choose
Outdoor rating first
Only the TrioBliss and KEN BROWN list indoor and outdoor use, while the Hurricane lists indoor use only. The TrioBliss has a weather resistant motor for window mounting, and the KEN BROWN lists patios, garages and shops among its uses. Check whether the fan lists outdoor use before buying for outdoor use, since airflow alone does not make a fan outdoor rated.
Compare airflow in CFM
Airflow separates these fans: the KEN BROWN moves 4,700 CFM, the Hurricane moves 2,400 CFM and the TrioBliss moves 1,710 CFM. A higher CFM figure means the fan moves more air, but size and tilt shape where that air goes. The KEN BROWN adds 360-degree tilt, while the TrioBliss reverses airflow for windows. Compare CFM alongside tilt and reversibility when you choose.
Controls and portability
The Hurricane uses push-button control with a slim frame and adjustable feet. The KEN BROWN uses push-button control with a handle and nonskid positioning. The TrioBliss uses top-mounted controls with a carry handle that moves the fan between rooms. Weigh the controls against how much you move the fan.
