All of these studies come to the very obvious conclusion that a good hood fan, that vents outdoors, isn’t optional. The scary numbers, as in this study, come from not using a hood fan, with “good hood fan” numbers being somewhat negligible. I think a good middle ground (since you can’t ask everyone to rewire their homes for electric) would be some sponsored program to install heat detecting hood fan switch, so they can’t be left off by mistake.
