As mask are used frequently by common people,so it would be better to use cloth mask and can be washed with detergent ,so that it would be disinfectant and reused also. So that problem of disposal remains minimum.Also medical staff used ppe should be disinfectant properly.Also where patient has put, waste of them PPE,water used etc should be disinfectant properly to avoid any chances of spreading.
Dear Dr. Veerender Sharma,
Technological process of PPE decontamination by UV Germicidal Irradiation exposure can be used for safely decontamination of cloth masks, that can be reused. This technology has been efficacious in sterilizing masks for reuse H5N1 infection. I propose the decontamination of cloth masks as well as all infected areas at risk of COVID-19 by UV Germicidal Irradiation technology.
Best regards,

There are varying views on if respirators could be re used after disinfection. This is especially true given the current situation where there is extreme demand. There are some studies and opinions which suggest that this could be done. For example, treatment of Face masks with Hydrogen peroxide vapours or Chlorine Dioxide gas has been suggested to be an appropriate method, without a significant loss in quality of filters. However, It is unsure how many such cycles can be done. Most likely this method cannot be repeated for more than 3 times.
