Laminar Flow Cabinet Build

[Afid]

I recently built a laminar flow cabinet for seed flasking and I thought I would share some pictures and info on its construction. I just used it for the first time today and it seemed to work great! Long story short, I took a clean room filter (from a photography lab I think) and built a coroplast box around it with a plexiglass front. I also added a pair of furnace filters at the intake vents to block any larger stuff from getting into the more expensive filter.
