There are some great smoke eaters/air purifiers out there that can handle cigars.
A cigar podcast I used to listen to had one of these linked below installed in their "studio" and they said it was awesome. For a couple hundred bucks, it might be something to look into.

Thanks for the link and suggestion. That may be a good add on to the exhaust system I want. I'm looking to put an exhaust system off 800+ CFM and then some else in the room to purify the air to get out the residual smell that's left behind after the smoke is extracted.
