What type of respirator does not use cartridges?

A dust mask is considered a type of respirator that does not use cartridges, as it is typically a simple, non-powered device designed to provide limited protection against particulates such as dust and allergens. Dust masks are usually made of a lightweight material and are primarily intended for use in scenarios where there is minimal exposure to harmful contaminants.

In contrast, options such as filtering facepiece respirators, half-mask respirators, and full-face respirators incorporate filters or cartridges that are specifically designed to capture a wider range of airborne contaminants, including gases, vapors, and particulates. These respirators are used in more hazardous environments where higher levels of protection are needed. Therefore, the distinction lies in the level of protection provided and the components used; cartridges are a critical feature in the more sophisticated types of respirators, whereas dust masks operate on a more basic principle without this added layer of filtration.
