Workshop Airborne Dust Filter

This morning I finished and hung a homemade airborne dust filter in the workshop.

I had a fan blower sitting around from an old above-the-stove microwave thanks to an unnamed household member. The microwave was run for several minutes with no food inside – which didn’t help the microwaving part. But the vent fan was fine. Ben and I took the microwave apart a few years ago, and the fan has been sitting around in my shop waiting for a project.

I had to order a filter, switch and a starting capacitor (since I apparently didn’t save one from the microwave). The plywood was left over from another project. After being distracted way too many times, I finally got the project finished today. It has two speeds wired in, but no labels on the box (yet).

I’ll see how much dust the filter collects, which hopefully reduces the dust my lungs collect.

Air filter assembled and hung above the tablesaw. The blower exhausts on the left side of the box.
Fan blower and wiring – the wiring harness from the blower didn’t leave a lot of room to work with.
