It's also remarkable that none of these pieces (and this is no exception) ever seem to talk about proper air extraction. You would have thought that would be the first thing anyone researching this topic seriously and objectively would look at. The relative damage done by pollutants emitted by cooking oil and food on a stove (regardless of type) is also rather larger and better documented (though still not huge in the grand scale of things), which gives another reason to talk about extraction.
