Reusing Manufactured Medical Masks

1. It was found that dry heat disinfection (heating at 70 ℃ for 30 minutes) had the least effect on damaging the filtering mechanism, and the filtering effect could be maintained above 95%.

2. The disinfection method of spraying alcohol on the mask will destroy the electrostatic absorption of the mask, causing filtering efficiency of the mask lowering below 95%.

3. Other methods such as steamer damp heat method and high-pressure high temperature sterilization methods also made the filtering efficiency of the mask lower than 95%.In addition, high temperature and high-pressure method makes the mask seriously deformed.

4. The new coronavirus is sensitive to ultraviolet rays, and ultraviolet disinfection does not affect the filtration efficiency of respirators. However, the inactivation effect of viruses in mask fibers, which cannot be directly observed, is unknown. Therefore, it is not recommended.
