FWIW a 24" wheeled shop fan from Harbor Freight, Tractor Supply, Rural King, etc etc (sometimes HD/Lowes have them) move way more air with more authority than a box fan. They will run $150 but they can be very useful to have around even when you don't need to filter the air. (Note the motors pull more current so you still have to be careful not to overheat them) Some examples: https://www.harborfreight.com/merchandising-promotions/hot-buys/24-inch-high-velocity-shop-fan-93532.html https://www.harborfreight.com/merchandising-promotions/hot-b... https://www.tractorsupply.com/tsc/product/countyline-24-in-direct-drive-tilt-fan-bf24tfcl https://www.tractorsupply.com/tsc/product/countyline-24-in-d... https://www.homedepot.com/p/Commercial-Electric-24-in-Heavy-Duty-2-Speed-Direct-Drive-Tilt-Drum-Fan-BF24TFCE/303061463 https://www.homedepot.com/p/Commercial-Electric-24-in-Heavy-... Axial fans are still better for this application, but these fans are great to have around in summer evenings when the air outside is cooler than it is inside. Put it in one window of the house sucking the air outside, then open windows on the other end of the house and let the cool night air stream in. It's fantastic.
