DIY Air Cleaner for Woodworking

I wanted to make my own air cleaner with a box fan but make it capable of holding two filters so I have the option of using course and fine filters simultaneously. I made this from 3/4" plywood, a cheap $15 20" box fan, and two 20x20 house filters. I also added casters so it can easily move around the shop.
