The KN95 mask is an efficient respiratory protective device designed to filter airborne particles and contaminants, including bacteria, viruses, and other harmful substances. Constructed with multiple layers of high-efficiency filtration materials, it effectively blocks the majority of tiny particles in the air, protecting the wearer's respiratory system from pollutants.
Typically, the outer layer of this mask is made of waterproof material, which prevents the penetration of liquids and droplets, thereby reducing the risk of disease transmission. The inner layer consists of high-efficiency filtration materials such as polypropylene and cellulose, capable of filtering out tiny particles in the air while maintaining breathability and comfort.
KN95 masks boast a high filtration efficiency that meets international standards, making them commonly used in healthcare, industrial production, public spaces, and personal protection. However, it's crucial to ensure their effectiveness by correctly wearing and handling them, including proper positioning and timely replacement.
