The N95 respirator masks is designed to filter as much as 95% of airborne particles 0.3 microns or bigger that may otherwise directly enter the nostril and mouth of the wearer. These masks might also be worn by individuals who have a contagious illness to forestall particles from leaving the nose and mouth of the wearer and placing others at risk.
