Do you just set it next to your project and let it catch what it catches or
do you have a box or "wind tunnel" type of set up?

When I'm sanding I have a 20" box fan setup on my bench with 2 filters. I
have the good 3m filter (forget how small a micron it filters but it gets
pretty fine). then I have a cheap fiberglass filter outside of it. I made
like a J-channel for them to sit in then tape the edges to keep it sealed.
Does a pretty good job.
