It is not soot that is the worst problem as that can be filtered out reasonably well (80-90%), generally being 1-10 µm. It is the aerosol particles in the range 0.01 - 0.5 µm which are invisible and float suspended in the air for days, if no one breathes them in. They pass through the filters without hindrance.
