I always considered my roll ups were filtering out a fair bit of dust.
I shouldn't joke, fortunately I'm still running and I don't have any diagnosed lung conditions but I've mostly never worked on building siters per se. I'm usually working alone so at least I can control the broom.
At the moment I have 4 extractors of varying sizes, 2 of them M class. Mostly I got those to save the people around me from dealing with the dust that my job creates though.
I do agree with @Nef though, it does feel like I am trading my health for a few coins, too few generally. On the other hand physical work can keep you in better physical shape than office based work.
It's interesting (albeit morbid) to speculate how many of these conditions we are only really finding out about now, as the people that would have got them in the past generally wrecked their lungs by smoking before any of these presented themselves.
