Air flow helps tremendously. You want to move the overspray out so you can see. You also do not want the overspray landing on the completed areas. A couple of little box fans and a small hole in your tent do not cut it. The box fans will draw the air around the corner of the box. You need to fill the corners and open up the tent to allow for lots of air flow. A whole house fan and lots of holes in the tent work well. Do not worry so much about the dust. Most of the dust really comes from the part you are painting, and from yourself.

Air flow within the spray booth helps tremendously. The goal is to move overspray out, maintaining visibility and avoiding overspray landing on completed areas. A couple of little box fans and a small hole in your tent will not cut it. The box fans will draw air back into the booth around the box corners. The corners should be filled, opening up the tent to allow for lots of air flow. A whole house fan and lots of holes in the tent work well. Do not worry so much about the dust most of which comes from the part being painted as well as the painter.
  
More air is also a safety issue. If you are using organic cartridges in your mask, then the less vapor hanging out in the booth the better. Organic cartridges need to be fresh. They have a time rating on them and the charcoal fills up eventually. The biggest exposure to bad chemicals is though the skin and through an improperly fitting mask. A supplied air system and coverall suit is the smart thing to do. Yes, the air units are pricey, but they have a good resale value, so think of it as a rental. You can resell the unit later and make a lot of your money back. The suits are cheap and help prevent the dust that comes from your clothes.

If your booth is attached to your house then you need to be sure that the occupants of your house are not exposed to the fumes. Use the fans to create a negative pressure in the garage area. You might be surprise at the pressures that small and medium sized fans can produce. Try using a roof vent fan to push air out.

If the booth is attached to a home, cre must be taken to ensure that the occupants are not exposed to fumes. Use out-flowing fans to create a negative pressure (suction) in the garage area. You might be surprised at the pressures that small and medium sized fans can produce. Try using a roof vent fan to push air out.
