We were smoked out of our last house by the neighbour installing a wood burner in their bungalow. We were right in the fume plume, so got pretty ill. They couldn't work out why were unhappy as they couldn't smell it.
So I know a fair bit about the stats for the ill health results of this. For all the "it's natural" people, there was a reason for the clean air legislation last century. When even smoking fags was allowed...
I can also smell it on clothing & the dog, so I'll agree some people are more sensitive but we are your canaries, folks.
Interestingly, we moved to an area with less pollution (again) but now pretty much every house has one & it stinks.
Like every van owners says they don't dump their shit, everyone with a woodburner says they burn dry wood. Which is bollocks as you can smell fence painted wood & wet shit, not to mention coal, as you wander around the town.
People really don't always burn at the correct temperature & bank their fires, which is terrible for fumes, too.
However, like legislation for the obesity crisis, it's difficult as for every recreational fire, there's one for the reasons other people on this thread have shared like living rurally or sheer cost of living.
So it's really difficult but next time you're out for a walk, look upwards & look for the chimneys with little mesh hats, they are getting ever so much more common.
