How long does the medical mask take to change？
If the mask is used for a long time, the protective effect will not be as good as it was at the beginning, especially the medical staff, when the time is up, replace it with a new one. So how long can medical masks generally be used?
How long a medical mask can be used depends on the situation, but generally disposable medical masks need to be replaced every 4 to 6 hours. For ordinary people in their daily lives, if they do not go to crowded places or go to the hospital to see a doctor, medical surgical masks are usually replaced every six hours. Of course, it can be extended appropriately depending on the situation, but it is generally not allowed to wear it five times, and it is best not to exceed 24 hours.
For medical staff who wear N95 masks during their work in the hospital, such masks are generally replaced every 4 hours. If the mask is contaminated by foreign matter, it needs to be replaced in time.
Medical surgical mask
Generally within 4 hours. 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.
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.
If you are not a medical staff, it is best not to wear a medical mask for more than 24 hours. If you go to a hospital, it is best not to wear it for more than 6 hours. Medical staff wear masks for about 4 hours and need to be replaced. In addition, do not wear return masks. If you need masks, just click here to get more information.
