Do you know the service life of KN95 masks?
Editor：Zhejiang Antipollution Medical Equipment Co., Ltd. │ Release Time：2021-12-13
At this stage, there has not been a more accurate statement about the wearing time of KN95 masks overseas, including WHO, and there is no scientific research on the safety protection efficiency and wearing time of medical safety protective masks in my country. However, the data shows that the filtration efficiency of the KN95 mask is still maintained above 95% after wearing it for 2 days. The inhalation resistance does not change much, and the filtration efficiency is reduced to 94.7% after wearing it for 3 days.
The US CDC’s proposal is that when masks are in short supply, as long as the masks are not significantly contaminated or damaged (such as wrinkles or tears), they can be considered for continued application. When the following conditions occur, they should be replaced immediately:
1. When the inhalation resistance increases significantly;
2. When the mask is damaged or broken;
3. When the mask and face cannot be sealed;
4. The mask is polluted by the environment (for example, when it is stained with dirty things such as blood stains or droplets);
5. It has been used in hospital wards or touched by patients (because the mask has been polluted by the environment);
