The N95 mask, renowned for its filtration efficiency, blocks at least 95% of airborne particles, earning its name. It forms a snug seal around the nose and mouth, ensuring air passes through the mask’s filtration layers. Designed with multiple filtration layers, including electrostatically charged material, it captures particles as small as 0.3 microns. Widely used in healthcare, construction, and industrial settings, N95 masks provide respiratory protection against viruses, bacteria, and other airborne contaminants. Fit testing is crucial to confirm proper seal and efficacy. Available in disposable and reusable variants, they serve as vital personal protective equipment, safeguarding wearers from inhaling harmful substances during various activities.
