The N95 respirator masks is designed to filter as much as 95% of airborne particles 0.3 microns or larger that may in any other case directly enter the nostril and mouth of the wearer. These masks might also be worn by people who have a contagious sickness to prevent particles from leaving the nostril and mouth of the wearer and placing others at risk.
