I bought a squirrel cage blower for $30 and watched a youtube video on how to make this contraption. Here is the final project.

The box is made of MDF and plywood. I bought a timer that goes up 8 hours and shuts off (1,2,4,8 hr increments) from Amazon. The wiring wasn’t quite pretty but it does the job for my shop. I also have a two-way toggle to select low or high on the blower. I’ve never used the high setting.

There are two filters (20×20x1): a cheap one to replace every so often and a more expensive to blow out a few times before replacing. Basically, I picked a size filter and built the box to fit.

The last pictures shows a comparison of a clean filter and a filter after sanding for an hour or so.

Thanks for looking.

Try using the best filters money can buy otherwise, you risk the chance of blowing the more dangerous, smaller particles back through the shop.

Had a blower given to me some time back, been wanting to make something similar, though leaning toward a downdraft table that also works for a shop filter.
