Food smells coming from basement?

range-hood-bgeraserturds asks:

I tried a couple searches and nothing really seems to fit my situation.

There are tenants that live in the basement and every time they cook, the smells come up in to the main floor. I think the smell is making it's way through cold air return in to the basement straight up to the cold air return on the main floor.

Is there anything I can do to stop this? It can be pretty strong at times.

Answer: I would think the smell is wafting through the floors. Each apartment should have individual heating/Ac units and should have their own returns and should not be tied together. A range hood vent outside over the stove might help reduce the odor.
