Respirators are primarily used to protect which part of the body?

Respirators are primarily designed to protect the lungs from airborne contaminants, including dusts, fumes, vapors, and infectious agents. The primary function of a respirator is to filter the air that the user breathes, ensuring that harmful particles do not enter the respiratory system. By fitting snugly to the face and creating a seal, respirators prevent inhalation of these harmful substances, which can cause serious health issues including respiratory diseases, lung irritation, and even more severe long-term complications.

While protection for other body parts, such as the eyes, skin, and hands, is also important in hazardous environments, each has specialized protective equipment tailored for their safety needs. Respiratory protection is uniquely focused on maintaining clean air for the lungs, making it distinct from other forms of personal protective equipment.
