In the most general sense, a respirator mask is a device that prevents the user inhaling dangerous gas, fumes and vapors. It also provides protection from inhalation of dust and airborne biological pathogens. By inhalation, we mean any means of entrance into the body via either the nose or mouth. Some respirators also protect against invasion of foreign matter via the eyes.
However, within this broad definition, there are many subcategories. We set out below a high level description of the taxonomy of respirator masks:
The respirator masks in this section are all half face, air filtering, particulate respirators. They protect against non oil particulate matter of size roughly 0.3 microns and larger. For reference, 0.3 microns is roughly the size of a grain of salt. Specifically, these respirator masks do not protect against noxious gases, vapors or fumes.
