Cigarette smoke coming in from outside through HVAC return?


Smoke smell is shooting out of my vents from somewhere... I'm not sure where else it could be coming from. Ugh, I'll never understand why people smoke anymore! I've got air purifiers running, but apparently that just makes the problem worse when dealing with smoke. What I need to do is determine the source, and then eliminate it. >.<

I *love* Indian food - just not curry itself.

is the furnace/air handler in the closet ducted to that small vent in the picture:important...is the ceiling in the furnace closet solid or open in anyway.basically is the closet the return to the furnace with the door closed and does that door have louvers on it for the return air from your living space.question do you smell any cooking going on from the other tennents into yours?

Yes, that small vent is ducted to the return in the closet. The ceiling in the closet is closed, it looks just like the ceiling in the rest of the house. The return is located inside the closet (that's where the filter is changed, etc). The door just closes to keep it hidden. I've never smelled any cooking from my neighbors.

I did some research on some really good filters, and I've decided upon this one. I hope it makes a big difference. Once I have that problem narrowed down and fixed, I can scrub my condo top to bottom. Have I mentioned that I hate cigarettes? >.<

I would NOT use that filter. It is highly restrictive to airflow and the lack of airflow may freeze the AC coil and shut down your unit. Those filters require an extra powerful furnace fan, usually a variable speed ECM type and larger ductwork.

It *is* ducted for that. It sucks in outside air and that air is vented through my system. That's how the smoke is coming in.

still too tight/restrictive. there is NO air filter like those that will take out smoke. that is "creative advertising". An electronic air cleaner will but it is no different than the electrostatic room air purifiers. an eac has ionizing wires in it the same as those room jobs. they attach to the return duct. flip side is they give off an ozone smell (like smog or fresh rain smell) which a small per cent of people can smell and don't like. they also sound like a bug zapper. we use eacs in bars and bingo halls etc. there is no other method that I know of.

Surely a new and better filter will at least improve things, yes? I'm a bad girl and haven't changed my filter in forever. Out of sight, out of mind. X_X

OHHHHHHHHHHHH that needs to be capped off so you get the true space return and nothing outside.how do you cool or heat the space $$$ bringing that in.is it accessable within that closet connecting to the return duct?when any supply fan runs it pulls the air from the least resistanced place........your outside stoop area.

Open the closet door and take some pics of your furnace/air handler and post the make and model #. MOST units do not take outside air as it is too cold or too hot or humid and take it from the house. a small fresh air pipe is sometimes installed but the majority of the air is returned from the house to be reheated or cooled. not sure why you are taking so much outside air or if it is even necessary.
