When masking is recommended, individuals should wear a mask while indoors except while eating or drinking.
An upgraded mask is defined as a well-fitting, non-cloth mask with multiple layers of non-woven material with a nose wire.
A highly protective mask is an upgraded mask or a cloth mask meeting ASTM standards for high filtration efficiency (ASTM F3502-level 2). When masking, please consider wearing medical/surgical, N-95, KN-95, KF-94, or cloth masks meeting ASTM standards for high filtration efficiency (please be sure to consider whether N-95, KN-95, and KF-94 masks are the right size for younger students).
Additionally, LACDPH states that, for those wearing surgical masks, double masking, with a cloth face covering worn over the surgical mask, is recommended for enhanced protection.
