How can the mask be reused after use?

2021/03/26

Regarding the disinfection and reuse of masks, some scholars have proposed:

  Ultraviolet method

 

254nm wavelength, 0.3 mW/cm² light intensity, 30 seconds.

 

Dry heat method

 

70°C for 30 minutes in a medical drying oven. (Disinfection cabinet can be used at home)

Both of the above methods can be fully disinfected and still meet the N95 mask test standard.

 

However, the Centers for Disease Control also suggested that ordinary people are not recommended to reuse masks.

 

In addition to wearing a masknose wire, always remember to wash your hands frequently
