•Filtration Efficiency: KN95 masks are designed to filter out at least 95% of airborne particles, including viruses, bacteria, and other pollutants, with a particle size of 0.3 microns or larger.
•Design and Fit: KN95 masks have a 5-layer structure, including a non-woven fabric outer layer, a melt-blown filtration layer, and a non-woven fabric inner layer. The mask is designed to fit tightly around the face, covering the nose and mouth.
•Respiratory Protection: KN95 masks provide respiratory protection by filtering airborne particles and reducing exposure to harmful substances present in the air.
•Certification: KN95 masks are certified by Chinese standards and are regulated by the National Health Commission of China. They are considered an equivalent standard to the N95 masks used in the United States.
