Can I still use an expired mask?

Many people may think that although the shelf life is marked on the outer packaging of the mask, it is not an oral medication and is at most a medical device. It can continue to be used even after the shelf life has expired, but the actual situation is not the case. The meltblown layer in the middle of the mask actually plays a filtering role. During production, special equipment will be used to make this layer of meltblown cloth carry static electricity. The static electricity can more effectively absorb particulate matter, thereby achieving the purpose of protecting the user. If the shelf life is exceeded, the static electricity will gradually disappear and the actual function will decrease. In addition, although the masks have been thoroughly disinfected before leaving the factory, they are still at risk of contamination if they are stored for too long and exceed their shelf life. So from a professional point of view, expired masks are definitely not something that people can be completely assured of.

How long is the shelf life of masks

I believe many people are now very concerned about how long the shelf life of masks is. In fact, the shelf life of brands from different manufacturers and with different specifications is not the same. However, the shelf life of most products can reach more than two years, and some products can reach 5 years. If you find that the masks at home have just expired, but you don’t have any other masks on hand, you can use them temporarily, but be sure to be careful not to go to places where there is a risk of infection. Of course, this is for ordinary people. For professional doctors, this practice is strictly prohibited.

Can expired masks still be used? The above analysis of this issue from a scientific perspective. Masks are indeed in short supply during special periods, but you should be rational when hoarding masks, otherwise you will only bring yourself unnecessary losses.
