Paint Booth for Full Respray

From watching certain youtubers on positive ventilation, youd want the fans to have an after filter to catch stuff and even then... Ive seen better results with just a negative vent set up as the positive air tends to blow particulate on the paint.

My main concern is evacuating the paint fumes/mist. The thought of being in a room that is full of toxic and potentially explosive fumes makes me nervous. I just feel that a negative pressure system will get the stuff out of there quicker. My theory is that the higher the concentration of paint vapours to O2, the higher the risks associated. I have two box fans and when I'm done, basically 1/4 the back wall will be a filter. I also have 2 pieces of 32" x 45" furnace hammock filter and will likely use it to cover the 6 filters for added filtration. That's 20 square feet of filtered intake and about 6 square feet of exhaust. I will play with the configuration until I get the best flow rate with maximum air removal and an acceptable pressure - aka not too much suction on the walls. Since I'm doing a base coat/clear coat, a few small dust particles are a minor concern. I will likely be wet sanding and polishing the clear afterwards anyway.
