For leaded smoke, I recommend using a P100 (HEPA) filter, such as a 3M 2091 particulate filter or a 3M 7093 P100 HEPA filter. P100 and N100 filters are suitable for this application. Lower grade (N95) filters will not stop these dangerous and toxic substances.

The N95 respirator is a respiratory protection device designed to achieve a very tight facial fit and very effective filtration of airborne particles. The “N95” designation means that when carefully tested, the respirator can block at least 95% of very small (0.3 micron) test particles.
