N95 refers to a National Institute for Occupational Safety and Health (NIOSH) score that’s assigned to masks that meet a specified minimum customary for particle transmission. The N95 respirator masks is designed to filter up to ninety five% of airborne particles 0.3 microns or larger that may otherwise directly enter the nose and mouth of the wearer. These masks may be worn by individuals who have a contagious illness to prevent particles from leaving the nose and mouth of the wearer and putting others at risk. While such masks don’t protect towards particle transmission with a hundred% accuracy, they can be efficient in preventing the spread of infection.
