So I am between jobs right now so I thought I’d knock out some of those projects in the back of my head. One of those projects was a shop filter made from a box fan and plywood scraps.
I saw a thread the other day about shop filters. I have always thought a shop filter would be nice to have, but I wouldn’t want to blow a bunch of money on one. So, like many of y’all, I decided to build my own. I made it out of some scrap plywood I had sitting around. I made the box so that the filters and fan can be removed from the side. Some wooden tabs hold a removable side piece on, and when you need to change the filter or use the fan, you just remove the side piece and take out whatever you want. I included in the box 2 places for 1” thick filters, 1 place for a 5” filter, and a place for the fan.

I hope to keep at least two 1” filters in it most times. I made the spot for the 5” filter so that one day I can put a 20”x20”x5” MERV 16 filter (which catches 99% of .3 to 1 micron dust) in it. Those filters alone are about $100, but one per year isn’t too bad. I am hoping that a “sacrificial” 1” filter in front of it will help get most of the big stuff and prolong the life of the fancy filter.
I built this project because I felt that it could do almost as good of a job as a fancy rig with a few cheap filters. With the MERV 16 filter in it, it will outperform $700 machines. Hope you guys like it.
