One of my good friends is Glenn Haege, America's Master Handyman. He and I discussed what I should do for my mini-mancave for the winter months as far as keeping the air breathable for the rest of my family, who also use the area for cigarette smoking and don't care to be inundated with cigar smoke.
He has been instrumental in helping designing the air exchange systems for a few of our local B&M smoking lounges. The main thing, he says, is the number of "air changes per hour" (ACH) in a smoking room. He suggested a couple of products to me:
The
Panasonic Whisper Air Exhaust System which can be sized to your paticular space. They make these for ceiling or wall mount. The link above shows the various models, but you should talk to someone locally to find out exactly what size you need.
For an air cleaner he suggests the
Amaircare Corporation. This company is based in Canada, and will ship to the US if there are no local dealers (there are none here in Michigan). I'm even considering buying the smallest one that hangs on the back of the front seat of your car and cleans most of the smoke up instantly.
If you want to check Glenn's website, it's
MasterHandyMan.com.
You'll also want to make sure the door has a good seal and that there is NO cold air return in the room, as either of those will have cigar smoke all over the house.
Good luck in your project!!
