I hope this doesn’t turn into rambling nonsense. I moved into a new house stich had a room with no window. I declared this my room and titled or the bunker. Now my delima. Where do i vent the spay booth. The idea i have been toying with is running duct work into the ceiling and over to the unfinished part of the basement. Which would terminate in a box retrofitted with filters. I hope this makes sense.

Ideally you want your ducting from the spray booth to exit the house. Your plan will just move fumes from one room to another inside the structure. Not a big deal if you plan on using only acrylics. But if you plan on airbrushing enamels, lacquers, or other solvent based products it becomes one. If youre routing ducting into the ceiling, a better solution would be to have it exhaust via some sort of roof top vent like for a bathroom fan, heater, stove, or other such appliance.
If you bought the place how about a dryer vent setup on the outside wall (if the room has one) where you set up your booth.
I’m on about round three of the same detail. I get one of those dryer vent deals with the flap. Cut a hole in an outsdie wall. Attach it to the hood with 4" flexible duct.
Agree with the above posts, vent to the outside for complete removal of all fumes. For my use the spray booth has a powerful in line fan, lots of air flow, filter is the full size of the back of the booth. Fan is explosion proof. Four inch flex metal duct takes air to outside of garage.
Regardless of paint type, the cleaning agents you will use for cleaning airbrush, brushes, tools, etc, will likely be as harmful or maybe even worse than the paint itself. Best to get those agents out and away from the house, simply moving them to another area is not a reliable solution.
My booth is home made, the filter gets lots of residue buildup on it, so to be cautious I remove it from the booth and store in a big sealable plastic bag, until next use. The filters are about $3.00 at the hardware store, so I just change them frequently, about every ten painting sessions.
I think a filter contaminated from use is capable of leeching risky fumes, even though less than those from painting or cleaning, so keeping them sealed between uses seems a good practice to me. Just a suggestion, but don’t forget to wear a mask while painting or cleaning. You’re only issued one set of lungs.

Thanks for the responses and i will find a way to vent to the outside
If you have a good filter in your booth, the perceived vapors in the air will seem less. The solvents evaporate very fast from small airborne particles due to the high ratio of surface area to volume and hence mass. The vapor will evaporate slower from the surfaces of the filter. So if the problem is reducing objectionable smell, even an unvented but filtered booth will help that. If your concern is the health, however, it is likely the total vapors in the long run will be the same. I have no idea whether there is a minimal amount that creates a risk, however. That is, is there some level of vapor that has no health hazard but above which there are health consequences?
