It's not just the fumes that cause problems. The overspray is super fine and it will collect on everything. It is best to use a spray booth that exhausts outside. I don't think the aquarium charcoal will cut the fumes.
If you have an electric cloths dryer, you can use the same vent. I put a Y in the exhaust vent line and use a blast gate to direct the spray booth out only when in use. It allows me to close it off when not in use. Minimal amount of heat loss!
