The emergence of COVID-19 makes masks a popular commodity. It is difficult for drugstores to buy masks any more, even if they are available, they will limit the purchase. Some people will wear disposable masks for a long time to save masks.
How often is a disposable medical mask changed?
Ordinary disposable masks purchased in general drugstores cost about 1 yuan. Such masks cannot be used for a long time. In general, it is recommended to replace disposable masks every 4 hours.Only timely replacement of masks can achieve a better preventive effect.
Different types of masks can be used for different periods of time. Masks of N95 level and above can theoretically be used for 1 to 2 days. Disposable N95 masks cannot be reused after they are removed.
The maximum use time of disposable surgical masks is 4 hours, and should be replaced immediately after getting wet.
If you really can't buy a mask and want to reuse it for many times, it is recommended to use high concentration of alcohol to sterilize it before drying it.But I strongly recommend that you don't reuse it.
The above is the answer about the use time of disposable medical masks. I hope you will like it.We are a professional disposable mask factory, welcome to consult to buy ~
