My wife prefers a non smoking house, but I must admit that I do as well. However, I still smoke inside, I just do so next to a cheap double blade window fan that I take in and out whenever I smoke. It happens to be next to our kitchen table and I sit comfortably a couple of feet from it. It works perfectly, and there is rarely any lingering tobacco scent at all. When there is, it always very light and goes away ina few hours. Even in winter I doubt it affects my gas bill that much, and if so it's worth it
