Just about anything will capture overspray, but you really can't do much about vapor getting thru. "Dilution is the solution" for that. And where your shop is, no one is going to smell the vapors.
Or are you talking intake filters? Again, unless you're in a really dusty environment outside the booth, probably the least expensive filters will do the trick. You'd probably do fine with a MERV 8 rated filter that's 1" thick. The thicker you go, the harder your fan has to work.
It looks like the paint booth guys sell fiberglass filters that have sticky stuff on them, but you may not need that. The MERV rating is an HVAC thing for commercial ventilation system filters.
