Went to my local Home Depot and was asking about a smoking room. Just my luck... I ask a guy who's a cigar fanatic who built a smoking room for his house just a few months ago. :thumbs:
He says the most cost efficient way to do it is to stay away from those ionizers and the like. They do minimal work for a premium price. Basically, its a matter of physics. Create enough of a low-high pressure air system, and it essentially cleans the room air for you. For my room setup, I weather stripped the store and added a seal to the bottom. The only vent in the room is exit only (ie: no return). I open my window and prop a box fan up to it. I face it out, turn it on high, and DAMN! instant vaccuum. I mean... I was skeptical at first, but wow, the smoke gets sucked right out and fresh air comes right in. The best part? The smoke is kept out of the rest of the house.
After you're done smoking, you'll still get a little bit of the smell lingering in the air. There's this spray you can buy called Oust. It eliminates the bacteria and odor produced by smoke. You give the room a good spray before you leave, give it 10 minutes, it's all gone. It's not like other sprays where it just masks the smell and all the residue is left, this spray actually eliminates it. Some of the smoke will remain in your carpet. Arm and Hammer makes this great carpet stuff that eats it right up. Much like Oust, it doesn't just cover the smell, it actually eliminates it. Just spray on the carpet and vaccuum it up.
Keep in mind, this setup DOES work... however, not for heavy volumes of smoke. If you smoke 1 or 2 twice a week, then this will be no problems. If you smoke 1 or 2 everyday AND you have a poker night every weekend, then no, this will not work.
So in summary: a bottle of Oust, a bottle of Arm and Hammer carpet cleaner, a box fan, and sealent for your door. Done. :thumbs:
