Smoke unfortunately is simply an man made component that's added to the air. It disperses to try and fill the entire enclosure with smoke. It is unlikely you'll be able to overcome this with any degree of ease. The building is constructed like a human body, with a skeleton (the building frame) on the inside and the 'skin' on the visible parts of the room. Just as you cannot see your bones, yet they are all connected together, such is the construction of your home. All the framework is interconnected and smoke/air will travel readily between units and especially where there is a 'chimney effect' of warmer air rising into cooler air. There are some electronic air cleaners that could be installed in your HVAC system to help alleviate the smoke smell from your unit. You'll want to shop carefully for such products as most (despite manufacturer disclaimers) require professional cleaning to keep the operating properly. Simply putting the cells in the dishwasher no more cleans them than soap and water used to clean an oven! There are some models that have replaceable elements and those are to what I would suggest you direct your attention.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
