N-95 respirator
N-95 Respirator
The N-95 respirator (pronunciation: /ɛn naɪnti faɪv ˌrɛspəˈreɪtər/) is a type of personal protective equipment (PPE) that is designed to achieve a very close facial fit and very efficient filtration of airborne particles.
Etymology
The term "N-95" is derived from the classification system used by the National Institute for Occupational Safety and Health (NIOSH). The "N" stands for "Not resistant to oil," and the "95" indicates that the respirator is 95 percent efficient at filtering out particles that are 0.3 microns in size or larger.
Usage
N-95 respirators are commonly used in healthcare settings and are a critical tool in the fight against airborne diseases such as tuberculosis, SARS, and COVID-19. They are also used in industrial settings to protect workers from inhaling harmful dusts, fumes, vapors, and gases.
