USNIOSHN95
USNIOSHN95 is the designation used to refer to NIOSH-approved N95 filtering facepiece respirators in the United States. The N95 classification indicates that the respirator filters at least 95% of non-oil aerosols under specific testing conditions, typically using a sodium chloride aerosol. These respirators are designed to fit over the nose and mouth to reduce inhalation of airborne particles and are used across healthcare, industry, and emergency response settings.
Certification and standards: NIOSH certifies these respirators under 42 CFR Part 84. Models receive a TC-84A
Fit and usage: Proper fit is essential; many workplaces require fit testing and a user seal check
Limitations and considerations: NIOSH certification confirms filtration performance but does not guarantee protection in all settings.
