How Long Can Disposable Masks Be Worn?

Under normal circumstances, disposable masks are replaced once every 8 hours, and cannot be reused.

The disposable masks are made of 28 grams of non-woven fabric with more than three layers; the mask part close to the bridge of the nose is made of environmentally friendly plastic strips. It does not contain any metal, and it feels breathable and comfortable. It is especially suitable for electronics factories and daily use. The disposable medical surgical mask can prevent respiratory tract infection to a certain extent. It is made of two layers of non-woven fabric and filter paper. In the middle of the two layers of fiber non-woven fabrics professionally used for medical treatment, a layer of filter dissolving spray cloth with an antibacterial control of more than 99% is added, and then ultrasonic welding is performed to produce a mask.

What needs to be reminded is that disposable masks are divided into various types according to the mask making materials, and the selection must be based on different operating needs and working conditions. For example, during an epidemic, medical surgical masks must be selected, and proper wearing methods should be noted. First, wash your hands before wearing a mask. When wearing, hold the ear cord with both hands, with the dark side on the outside and the light side on the inside. Place the side of the mask with the wire (a small strip of hard) on the nose, pinch the wire according to your nose shape, and then pull the mask completely down to cover the mouth and nose completely. In addition, such masks should be used within the validity period, which is limited to one-time use and should be destroyed after use; if the packaging of the mask is damaged, it should be prohibited.
