For this post, I have put together a collection of the best window fans currently available.
UPDATED: May 25, 2021.
MY TOP PICK:
If you are looking for the best overall, I recommend the AirKing 9166F because it offers the ability to close the window behind the fan for weather or security and features a three-speed motor that provides up to 3,560 CFM.
These fans offer the ability to provide a quick cooling solution by simply inserting the unit in an existing open window. The specifics vary by manufacturer but most units are equipped with adjustable screens on the sides to fit within a range of window sizes. These can typically be oriented either vertically or horizontally depending on the window type.
One common feature to consider when selecting a model is if the fan is whether it is manually or electronically reversible. Some units offer the ability to change the direction of the airflow with a switch, while others need to be manually turned around in the opening.
Obviously, the electronic option makes it easier to quickly switch from exhaust (blowing air out) to intake (blowing air in). Fans with multiple blades may even have the option to operate one in exhaust mode and the other in intake mode to create an exchange of air.

Another nice feature to have is a remote control, this can make it much more convenient to operate from a distance, for example, while in bed or on the couch. Also, built-in thermostats will turn the fan on or off based on the ambient room temperature.
