put a tower under all doors and over ventilation things (if you have to) and either put a fan near the window pointing out and smoke by it, or you can buy ozium. i love that stuff. its a gylcol based air sanitizer and a one second spray will remove almost all odors from a baked out room. if it doesnt work, just spray some more. i got my can of ozium at a sheetz by my house by other air fresheners
