The KN95 protective mask is designed for civil protection, helping you filter out bacteria, viruses, and pollutants from the air. It features a five-layer construction made of polypropylene, which includes a specialized melt-blown filter and an intermediate protection layer to achieve a bacterial filtration efficiency of at least 95% for particles 0.3 microns or larger. This white adult-sized mask uses a foldable design for easy storage and includes elastic ear loops for a secure fit. To ensure a better seal around the face, it is equipped with an adjustable metal nose clip, while the hypoallergenic materials make it comfortable for extended wear.
