How to use disposable masks

Disposable masks are very popular among people because they are cheap and easy to use. However, disposable masks often have a shelf life or validity period. If the validity period has expired, the mask cannot be used. Disposable masks are prohibited from being reused and must be destroyed after use. In addition, disposable masks are very easy to break, so you must be gentle when using them.

After using the mask, be sure to put it into a clean envelope. When storing it, fold it inward with the side close to your mouth and nose. Do not put it in your pocket or hang it around your neck. It should also be noted that disposable masks must be used within the validity period. Expired ones should not be used. They can only be used once and must be destroyed after use. If you find that the packaging is damaged when purchasing, you must not buy or use it. When purchasing, you must also pay attention to its production date and make sure to buy products produced recently.

The mask has two sides, white and blue. Turn the white side inwards and the side with the metal strip upwards. First, tie the two lower straps behind your neck and tighten them so that the bottom of the mask reaches the base of your chin. Pull up the straps on the mask so that the mask can cover the outside of the mouth and nose. The two straps on the top can be pulled behind the ears and on the head, and then tied tightly. Be careful not to tie them on the ears. Then use the index fingers of both hands to press the metal wire at the root of the nose on the upper side of the mask to make it fit closely to the skin of the nose. Then gradually move the index fingers to both sides to make the entire mask fit close to the facial skin.

The above introduces the use of disposable masks. It should be emphasized again here that disposable masks are generally used in room temperature environments. If it is in a high temperature and high humidity environment, disposable masks will not serve as a protective measure. Also, please note that if you find that a disposable mask is damaged when using it, then this mask must be thrown away and cannot be used.
