I've been looking for an air filtration system for my small shop for a while now. They are just to expensive for me to buy one. After looking online for some ideas I decided to make one. I used a furnace blower, some aluminum drip edge, and every piece of lumber scrap I could find in my garage. I had to use my tillering stick to finish it up.
I built the frame and used the drip edge for a channel to hold the filter.

I cut all the pieces to enclose it.

I mounted the frame to the ceiling

Installed the blower

Then I enclosed it and it was done. I have a temporary cord on it. I want to hard wire it in and put a switch on the side. It doesn't have a remote or multiple speeds like the expensive ones do but it moves a lot of air and will definitely keep my shop and my lungs cleaner.
