i've done paint in filthy shops that come out clean and clean shops that come out filthy. an exhaust fan really seems to make a huge difference with the amount of shit floating around in the air.
my old shop had a tube fan in the wall with the intake vent about 8 inches from the floor. sucked most of the dirt out of the garage down low so it wasn't floating up into the work. a little water on the floor just under the parts being sprayed and everything else in the shop was still filthy, but paint come out clean. a couple mosquitoes every now and then but not much dirt.
i had to spray some parts in the new shop before i had a fan in there and they were dirty as hell but the shop is cleaner than the last. also, painted block walls instead of posts and wrap.
a couple pounds of positive pressure is supposed to help too, that's how our booth is set up at work, but i haven't gotten that far in any of my garages. seems i'm always spraying with negative pressure in the room but it works.
