I have a solution for your problem. Buy a hepa filter, they work very well. A decent one cost like $100 at walmart (you gotta get a decent one). Put the filter right by the weed you are drying and close the door to the room you are drying it in. You wont smell shit outside of that room, been there done that. Just steer clear of Ionizers, they will take the smell and taste out of your weed. The only problem you could run into is a loss of electric ( I have had that happen and well within 10 minutes of losing power my place was stinking)
