Another name for the cartridge filter respirator is which of the following?

• A. gas mask
• B. N95 respirator
• C. full-face respirator
• D. dust mask

Answer: (D)

Understanding how respirator names are used in auto body contexts helps here. A cartridge filter respirator uses replaceable cartridges to filter particulates or vapors, and in many shop conversations and practice materials that protective gear is described in broad, everyday terms. The term dust mask is commonly used to refer to basic particulate protection, including what a cartridge-filter respirator provides for dust like sanding debris. So, in this context, dust mask is the familiar label for the kind of protective device that uses replaceable cartridges to filter airborne particles.

The other options refer to more specific or different equipment: a gas mask usually implies a full-face unit designed for gases with chemical cartridges, a full-face respirator is a type that covers the whole face (and may use cartridges, but is not the general everyday name), and an N95 respirator is a particular tight-fitting disposable mask with a specific rating, not typically described as a cartridge-filter respirator.
