I have a four-seasons room off the kitchen. It's about 14' X 16',
carpeted, insulated, high vaulted ceiling.
I want to smoke cigars in there during the winter, but I don't want
smoke to affect the rest of the house.
Can I close off the air return, and put a small fan in the window,
blowing out? Would this do the trick?
If this works out, I could go ahead install a dedicated fan higher up
towards the "peak" of the room.
