Multiple types of masks, such as KN95, can provide effective protection against novel Coronavirus. Medical masks are required for health care workers or those who travel frequently in high-risk areas.If it is daily protection, the protective level of industrial dust prevention particle masks is relatively high, but the protective level of disposable care masks is slightly lower. FFP2 and KN95 provide good protection in daily life. Then we may be very clear about how long masks can take. Next, let's give you a popular science about how long KN95 masks can take.

The validity period of Kn95

First of all, masks of KN95 level or above can theoretically be used for 1 to 2 days while disposable KN95 masks cannot be reused after being removed. Secondly, KN95 masks are well protected, but after wearing them for a long time, there will be an obvious sense of heart and qi. Well-known immunology professors have also warned that people should not wear KN95 masks for more than 4 hours at a time. If they use KN95 masks for a long time, they will cause lung damage and may cause emphysema and other problems.

In addition, medical face mask manufacturers suggest not to wear KN95 masks for children under 7 years old, even KN95 masks with special air valve design, because the respiratory resistance will be too great, and children have the risk of death. Some people have consulted experts about whether masks can be used repeatedly. Some scientific experts have clearly stated that no matter what kind of masks have a life limit, disposable medical masks are recommended to be replaced every 4 hours. The recommended duration of medical protective masks is about six to eight hours.
