The N95 respirator masks is designed to filter up to 95% of airborne particles 0.three microns or larger that will in any other case directly enter the nose and mouth of the wearer. These masks may also be worn by individuals who have a contagious sickness to stop particles from leaving the nose and mouth of the wearer and putting others at risk.
