How to choose
Match the width to your window
A vertical window fan must fit the window it sits in, so compare the expander range with your window width before buying. The shinic adjusts from 21.65 to 33.27 inches, the BLACK+DECKER from 22.5 to 33 inches, the Amazon Basics from 25 to 32 inches, and the COMFORT ZONE from 25 to 36.7 inches. A range that covers your window with room to spare gives a tighter fit than one that just reaches it.
Speeds, airflow and thermostats
Speed settings change how much air the fan moves, and airflow in CFM states that volume: 450 CFM for the shinic and 432 CFM for the COMFORT ZONE. A thermostat holds a set temperature by cycling the fan, while a plain dial only picks a speed.
Set it up for steady airflow
Mount the fan firmly in the window frame and extend the expanders until they meet the frame on both sides. Keep the cord clear of walkways and plug the fan straight into a wall outlet. Removable feet on the Holmes and shinic models let those fans stand on a flat surface when they are not in a window, and the COMFORT ZONE model arrives fully assembled.

Do these window fans have remotes?

What window widths do these fans fit?
