Those little "fume extractors" mentioned on this thread don't actually do anything. All they do is take the visible plume of solder smoke and put it through enough turbulent airflow to make it invisible- all the gunk is still in the room, as the tiny bit of token carbon-treated sponge is too insubstantial to do anything.
I've done air quality testing while soldering, with much bigger DIY versions of these "extractors" running. I've also tested with decent sized air purifiers running at full volume- they don't really do enough either in an enclosed room.
The only effective things are going to be extracting the air right outside, or using some kind of respirator (I now use a 3M respirator with VOC and particulate filters).
