Here's my air filtration system. It's been in place for a while, but I thought I'd share it since the topic comes up from time to time. It is comprised of six 12" x 24" filters arranged on a frame. It is driven by a 24" fan that I had left over from another project. The fan runs at three speeds, the highest is about 6000cfm. It provides a lot of filtration area, 12" x 24" x 6 = 1728 sq inches.
It hangs from the ceiling. Draws air in through the six filters and exhausts through openings on the front and rear. I put in a toggle switch for easy on/off.
Here's some of the build:
I use some of the higher-grade filters and clean them off outside when needed.
