Grey High-quality Fabric Capable Of Protecting Against Small Contaminated N95 Mask

The tight closure and the special fit are made possible by an adjustable nose clip. The two-legged design and welded double-point connection provide a reliable seal. Some models of n95 masks may have a raised plastic valve or seal that acts as a filter to prevent airborne germs from entering the user's lungs. Exhalation is easier than with traditional masks because the valves prevent moisture, heat and carbon dioxide from building up inside the mask. Viruses cannot escape from n95 masks with valves or inhalers. Being a "one-way valve", the valve protects only the wearer and not the aerosols that are discharged. N95 masks must contain a minimum of three or five layers of different materials.
