I saw this concept in a magazine, except they used a full box fan. Having limited head clearance in my shop (garage) I decided to go with the window fan and smaller filters.
I work with MDF a bit, and really wanted to get that out of the air, so I wouldn’t have to wear the mask quite so long. Seems to do the trick.
