I am dabbling with "positive pressure" paint room/spray booth.

I am only spraying Waterborne products.

My room is 16x20x 8 it is connected to another part of shop that is heated/air conditioned which is where i would draw the intake air from ...

If I set intake fans (couple of 20 inch box fans with filters ) near the ceiling, and a couple on the other end as exhaust fans near the floor would this be proper placement of the exhaust fans or do i want them at the middle of the wall for exhaust? Other suggestions also welcome.
