I have been very fortunate in that my wife is not bothered by the 1/2 dozen to a dozen cigars that I smoke a month, in the house - actually she often likes the smell. At the moment I live in an 80 year old house that is not exactly air tight and is heated by a forced hot air system that is pretty good at moving air through house. Even then, I sometimes pick up on residual cigar odors if I've been out for a day or so. That said, I just bought a new house - 10 years old, super insulated and tightly sealed. Heat is all radiant floors, ac has heavy duty HEPA filtration (the seller's wife was allergic to everything) and there is a air exchanger that moves air through the ducting when the ac is off. I just realized that smoking in the new house may not be such a good idea, as I'm not sure about the ability of the air exchanger to pull the smoke and odors out. If anyone has had experience with any of the standalone room air purifiers that are out there, I'd appreciate your input. Smoking on a porch in the winter, in New England, isn't going to work for me.
