N95 respirator or triple layer surgical mask: Radiologist perspective

Abstract

N95 respirators and surgical masks (face masks) are examples of personal protective equipment (PPE) that are used to protect the wearer from airborne particles and from liquid contaminating the face. The respirators are designed to reduce inhalation exposure to particulate contaminants (dust, mist, and fume). The authorities which regulate the quality control for the respirators are Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH), and Occupational Safety and Health Administration (OSHA).
