Amazon Basics Window Fan with Manual Controls, Twin 9-Inch Blades

It brings in a good stream of air and isnt too loud so as long as it lasts for a couple years I am happy with it. The one I bought has the ability to change the fan direction so it can exhaust or it can bring the air in.

You can hardly feel the air from this unit with both fans blowing let alone when you have one going each direction. Box fans are cheaper and provide much more air flow

THis fan is plastic mostly but I wanted to put it in my detached garage to circulate some air in the summer and it is very damp there so it is perfect for what I need. May not last as long but wont rust as quickly either.

Set these up at opposite ends of my room. One in the other out. Keeps my place nice and vool without needing ac.
