I've used the Febreeze Clip-ons for Cars with some success. They usually last a couple of months. Just clip to the vent. When really desperate, I have even put dryer sheets in the vents. It works for a few days.

I found an interesting discussion at Answers.Yahoo, especially in the Best Answer at the top of the page referring to Ozium \ smoke.

I remember well living above a smoker. He and his mother would sit out on the balcony and their smoke came up and right in our patio door. We had to shut it every time they were out there. Extremely frustrating. More and more new apartment buildings are smoke-free.

My aunt's condo had a heavy smoker and the smell would come in the vents.

How about a HEPA air filter?

You might want to give White Vinegar a try. White Vinegar is very inexpensive. Put bowls of it in each room. See if it rids your condo of the smoke odor.

Our condo board is attempting to make the entire property smoke-free. There are very few people who would vote against this, but it's hard to get people motivated enough to vote on anything. We need a 2/3 majority to pass the bylaws change.

The condo board was able to do some things without a bylaws change. No smoking is now allowed outside anywhere on the property, with the exception of a few designated benches that are placed as far from the buildings as they can be.

Only four of 316 condo units are currently owned by smokers. They may continue to smoke, but only indoors. The bylaws change would grandfather in the current smokers, but a new owner would not be permitted to smoke indoors.

What does your board tell you about passing some new smoking regulations? Perhaps they could pass a regulation that doesn't permit smoking outside.

jasdip, "my" smoker is also on the balcony below my own balcony and it is very frustrating. It seeps into the home and I can't keep windows open. chiuse, I have just petitioned my condo board to make this place 100% smoke free. It will be interesting how this plays out. We also need 2/3 majority in a 30 person condo complex to pass it. If it does pass I sincerely hope they don't "grandfather" the current smokers in.

Thanks for the suggestions. I have tried setting bowls of vinegar out and it DOES help. It is a great tip. But I'm just going to have to keep using any and all tips until the source of this noxious smoke is gone.

Can you open another window in your condo for fresh air that won't bring in smoke from the balcony below? I don't like to use the scents to cover odors because the odor is still there.

There are automatic air freshener dispensers that might help. Personally I have never used one but I've seen them in bathrooms at restaurants and department stores, and I've often thought that they had a fresh scent that wasn't overpowering. There are several listed on Amazon, you could check the product reviews.
