Not entirely sure, but a lot of these VOCs come from stuff in your house (carpet, paint, plastics).
When I lived in Augusta, GA the air around the city would occasionally reek due to a nearby paper mill. The smell would blow over the city after an hour, but anything that slipped into drafty homes would remain for hours; I'd only notice after returning from walking the dogs.
I started to wonder what I was breathing and found a list of possibile offenders: formaldehyde, acetaldehyde, benzene, chloroform, tetrachloroethylene, and trichloroethylene [1]
I was hoping my plants would help (the link nate_meurer posted casts some doubt).
