"Clean benches" are pretty neat, basically just a laminar flow ULPA panel filter with fans on top, mounted above a work surface. They are used in applications like hard drive disaster recovery labs - you don't need an expensive cleanroom, just plop a couple of these benches in an ordinary "dirty room" as they are called. As long as you open up the drive on the bench and don't remove it from the bench until it's sealed back up, you're good to go!
