Medical surgical masks, the longest use time is 4 hours, it is not suitable to use over time, and the mask should be replaced immediately after it gets wet during use, and cannot be reused. This type of mask is divided into a waterproof layer, a filter layer, and a comfort layer from the outside to the inside, which can effectively prevent the spread of blood, body fluids and splashes, and can prevent infectious agents (bacteria, viruses and other pathogenic microorganisms, etc.) with a diameter of less than 5 microns.


The difference between surgical masks and medical masks

1. Distinguish from the packaging

Generally, these two kinds of masks have different technical standards. The "Disposable Medical Mask" is (YY/T0969-2013), and the "Medical Surgical Mask" is (YY0469-2011). You can judge which type of mask the product belongs to by checking the implementation standards marked on the outer packaging of the product, and the respective names will also be written on the packaging.


2. Performance

Both types of masks can filter bacteria, but they are different in terms of water resistance and particle filtration efficiency. Disposable medical masks do not have performance requirements for water resistance and particle filtration efficiency, while medical surgical masks and medical protective masks have requirements.


Will it have an impact if the medical mask is worn backwards?

If the medical mask is worn upside down, it will not only affect the comfort of wearing, but also affect the degree of blocking the wearing of the mask against viruses and bacteria, which will reduce the protective effect to a certain extent. Therefore, when we use masks, we need to wear masks correctly to achieve the best protection purpose expected. At the same time, it is necessary to pay attention to the regular replacement of masks, so that the spread of the virus can be avoided more effectively.


In addition, the outer layer of a medical mask after use tends to accumulate a lot of dust and bacteria in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides of the mask cannot be used alternately.
