So it is official, I will now be a home owner. My wife and I are giving up condo living and bought a house outside Chicago to start the next chapter of our lives. While she is busy picking everything out for the house (her mother is an interior decorator) I have been busy creating my new office/ man cave. Working on the air filtration now. If anyone has any experience with air filtration or tips for smoking in the house, please send me a PM. I think I have a good handle but could use some seasoned advice. The man cave won't feel like much of an escape if the wife is going to nag me about the smell of cigar smoke LOL. As I get the construction under way, I will have to post some pics. So far I have a the bar, the desk, a small theater system that will double as video conferencing for some...... virtual herfing.... ah hum..... i mean business meetings via Skype and some comfortable seats etc. Oh yes and of course the cabinet humidor!

"Technical Information
The first challenge was to make sure smoke leaves via the exhaust fan to the outside of the house and not into the rest of the house. To do this I installed automatic duct dampers that close off the HVAC ducting and open up the fresh air intake ducting when you enter the room. There is one place to exit the smoke (exhaust fan) and one place to bring new air in from (fresh air intake). Both the exhaust fan and the fresh air intake have hoods that I installed to the outside of my house in my backyard that you can see in the pictures. The fresh air intake was an ordered item and the exhaust fan hood I had specialty made since the sizing I wanted was very specific.
In Michigan the fresh air coming in during the winters can be chilly to say the least, so I installed a duct heater into the fresh air intake. This unit has heating coils that temper the air as it comes in. There is a temperature sensor installed into the ducting so the unit only activates when the fresh air temperature drops below a certain point.
In addition to exhausting the air I put in a Csonka air purifier, which produces O2 for the room. This unit just ensures the odor of smoke does not linger in the room after the smoke is exhausted. The combination of this with the exhaust fan is perfect. You could smoke for hours on end, but within a few minutes of being done never know someone smoked in the room."

Then the only concern is to exhaust the air in the room as quiklly as possible, while keeping the air exchange seperate from the rest of the house. Using a good air purifier is also a very good idea, highly recomended. This is a pretty good article regarding the sizing of an exhaust fan for a smoking room.

I seal the door with weatherstripping around the edges and a towell at the bottom of the door, and put a plug (home made) in the central air warm air vent, and use a portable space heater to keep warm while using the room. The temp has never gone below 68 - and that was in the coldest part of the winter, usually, I have to turn the heater way down to stay comfortable (I'm fortunate to live in a climate with relatively mild and short winters). As I've already stated, I use a blueair air purifier sized for the room (which will run constantly during the winter months), and I let the exhaust fan run for about an hour or so after I'm finished.
As God is my witness, you cannot detect any indication that somebody has been smoking in this room.

in the other window or when it's not too hot I put in this air exchanger for intake and if it's cold use a small ceramic heater

when it's hot in the summer I put a small window AC unit in there instead of the air exchanger. Instead of the blueair purifier I have an AustinAir HM400 air purifier. Same thing when I'm finished I pull everything out of the windows open the door and leave the air purifier running.
Sounds like alot of work but it's really not. It works well especially since I didn't have to do any major home modifications.
also invest in an Oreck Air Purifier. turn it on when you are done. it should take care of any lingering odor.
Good job! You covered all the bases, probably for under $700. Exhaust is the key, and that window fan unit is perfect for a small room, probably something under 250 sq' with an 8' ceiling height. You're right about set-up and break-down time, too. I can be up & running in less than 2 minutes.
