The Helmet KN95 is a disposable protective mask designed for use in high-risk environments such as hospitals and health centers. It features a five-layer filtration system that captures up to 95% of non-oily particles larger than 0.3 microns, adhering to the GB2626-2006 standard. To make breathing more comfortable, the mask includes an exhalation valve that helps reduce the buildup of heat and humidity inside. The construction consists of a white non-woven polypropylene outer layer and electrostatic filter materials, while an adjustable nose clip and elastic ear loops ensure a secure fit around your face.
