I use Box Fan to move some warm air down the hall and tape 20x20 filter on it. It really traps some dust in Winter. But Tape is Ugly still (Clear Tape). Looking for some Clips. Here is the Files to Print your Own with 3d Printer. Alas I don't have one. But Library Does have one.

Clip to hold 20x20x1 furnace filter onto a 20" box fan. Use around the garage, makerspace, shop to help remove any dust/particles floating through the air. Setup while spray painting, using power tools, etc...Dont just rely on a dust mask. Keep your lungs cleaner.Wall mounts for the box fan...
