Laboratory masks are essential safety equipment in laboratories, primarily used to block pollutants such as dust, droplets, and aerosols. Common laboratory masks include surgical masks, N95 protective masks, and KN95 masks, with N95 masks filtering at least 95% of non-oily particulate matter. Laboratory masks typically use a multi-layered non-woven fabric structure and meet standards such as GB 19083-2010 or EN 14683.
