How to Wear a Mask
How to Wear a Mask0The letters and numbers on the packaging of masks, such as KF80, KF94, and KF99, show the mask’s capacity to block fine particles. When you put on a mask, reduce the gap between your face and mask by adjusting the nose wire to fit your nose. A mask’s exterior surface collects lots of microorganisms, like viruses and bacteria, so do not touch that part when you discard a mask. Wash your hands after you discard it.
