The first thing to do is to investigate the mask to see if it is the color, whether it is flat or not, and to check the light transmittance; then try the feel, mainly to feel the raw materials. If it is too hard or rough, it will be very uncomfortable to wear. When you buy a mask, you can smell it to see if there is any peculiar smell. If there is a peculiar smell, it is better not to choose such a mask as much as possible.

Wash your hands before and after wearing the mask; keep the mask close to your face: the colorful side of the mask is facing out, and the metal side is facing up. Tighten the power cord or wrap the rubber band around the ears to make the mask close to the face; the mask should completely cover the mouth, nose and chin; press the metal pieces of the mask along the sides of the nose to bring the mask close to the face.

Before use, you should carefully check whether the masks and masks are still intact. Regarding the gauze masks and masks, the light transmission method can be adopted, that is, take the light in front of the lamp to see if there are obvious light spots, and the light transmittance of the middle part and the edge part Is it consistent? If in doubt, replace it with a new one. In any case, face masks and masks are generally updated after cleaning 3 to 7 times, and masks of particularly good quality can be cleaned 10 times.
