How long can n95 mask be used?


N95 protective mask wearing recommendations:


1. After the replenishment of the mask, you should still wear the mask according to the principle of 4 hours replacement. It is still recommended to use surgical masks. The N95 can be replaced every four hours.


2. The replacement frequency can be appropriately relaxed and reusable in special periods. Depending on the frequency of use and the scene, it is recommended that the replacement frequency be changed within one to three days;


3. If the mask is not damaged, pollution and respiratory resistance increase significantly, it can be reused, but it is still not recommended to wear it continuously for more than 4 hours, because it will increase the respiratory burden and affect lung function;


4. Keep it in a safe place when reused, do not wash it (will damage the filtering performance);


5. When the following situations occur, be sure to replace the protective mask in time:


(1) The mask is damaged and the airtightness is damaged;


(2) The mask is sprayed with infected materials, such as being infected by sneezing droplets or other secretions of others;


(3) The length of stay in crowded places is too long or there is a clear history of contact between patients with suspected and confirmed cases. The maximum service life of masks does not exceed 8 hours;


(4) Breathing resistance increased significantly when wearing a mask.
