HEPA and Carbon Filters effective with Benzene and Toluene ...

It seems the HEPA filter is good at filtering out diesel exhaust. But not effective against some of the more toxic (carcinogenic) additives to gasoline such as benzene and toluene. My research also indicates that a regular carbon filter has minimal effect on those two additives as well.
