1. Note that there are two types of masks: medical and civilian. Civilian masks are mainly used for protection in daily life. Medical masks should be used during the new coronary pneumonia.
2. Go to a licensed pharmacy or a store that sells medical supplies.
3. If you buy online, you should also choose a well-reputed mall such as JD.com and Ali Pharmacy.
4. When purchasing, carefully check the manufacturer, production date, instructions for use, etc. on the packaging and the manual, and do not buy three-null products.
Precautions for wearing a mask (wash hands before putting on the mask, and before and after taking off the mask):
1. Make the mask close to the face:
(1) The colored side of the mask is facing out, and the side with the metal sheet is facing up;
(2) Tie the rope that fixes the mask, or wrap the rubber band of the mask around the ears to make the mask close to the face;
(3) The mask should completely cover the mouth, nose and chin;
(4) Press the metal sheet on the mask tightly along both sides of the bridge of the nose to make the mask close to the face.
2. After wearing the mask, avoid touching the mask to avoid reducing the protective effect; if you must touch the mask, wash your hands thoroughly before and after touching.
3. When taking off the mask, try to avoid touching the outer part of the mask, because this part may be contaminated with germs.
4. After taking off the mask, wrap it in a tape or paper bag, and then put it in a covered trash can for disposal.
5. Surgical masks should be replaced every day. If the mask is damaged or soiled, it should be replaced immediately.
