I simulate a paint booth in my garage - I run clear plastic from ceiling to floor, setup rolls of bug screen and 2x4's scrunch/sealed under the garage door, run a box fan with home furnace filters on it sealed in the rear door -and wet everything down with a garden hose - whole setup costs about $80 - walmart has large rolls of cheap plastic, home furnace filters, rolls of bug screen, plastic tarp hooks (to hang the plastic) and metal hooks to screw into the ceiling. I get box fans from the thrift store.
The setup looks like this:
