I recently bought a house and I've noticed that the upstairs often smells of cigarette smoke. I haven't actually seen anyone smoking outside, so I can't identify exactly where the smoke might be coming from. Is there a more effective way than filters for me to get rid of the smoke smell? Thanks.

Charcoal. Believe it or not. Put some charcoal brickettes on a paper plate and leave it in the area where you smell the smoke. It will help, at least temprarily, while you go find the smoker. Good luck.

Thanks again, Captain Rich!

But, even once I find the smoker, I can't keep them from smoking. Any long-term solutions?

I live in NE Florida where we are currently experiencing numerous brush fires. I put and electrostatic air filter in my a/c unit and afterwords inside the house you can't smell any smoke. The one I got was about twenty bucks or so, one size fits all. I cut it down with scissors and stuck it in. They say to pull it out once a month and wash and dry it.
