Living in the modern world, it can be difficult to avoid toxins. I drive a car, and this car, despite passing the smog test, gives off considerable harmful emissions. I don't really need to know what they're called, because its all very harmful. I am looking into buying a respirator for myself that I can wear while driving, in order to avoid getting a strong dose of chemicals everyday. Does anyone know a good brand/type/whatever, maybe aimed slightly towards car emissions or whatever?
