So, my oldest daughter, whom I live with, was complaining about the pipe tobacco smell that sometimes escaped my room. She's not looking for a better smelling tobacco... she want's no tobacco smell at all.
I basically live in my room, and the kitchen. I always keep my door shut and try to crack the window when weather conditions allow. But with the central AC and Heat positive air flow the smell will escape occasionally. I told her I'd take care of it.
So, this is my fix. It works fantastic! These computer case fans with variable speed controller and 120v connection can be purchased on Amazon in gangs of 2, 3, or 4. So I bought a gang of 3 and a gang of 4 and connected them for a gang of 7. I wrapped the entire edge with 3/4" x 1" closed cell weather stripping. As you can see, they fit my window absolutely perfectly. The rack comes out easily if I choose, but I'm fashioning a thin board blank that will slide down in front of the fans for nighttime and when it's raining, or when the fans are off.
With the speed set at lowest point, I can just barely hear the fans and it will evacuate the room of all smell and smoke in about 15-20 minutes. If I turn the fans higher it does the job quicker. There is a good airflow coming in around bedroom door with it closed, along with pulling ambient air through the duct work, so there is no way for smoke or the smell of smoke to escape my room. I've been using it for 5 days and she said she hasn't smelled anything coming from my room, so mission accomplished! Total cost $100
