Scientists have named the best way to disinfect medical masks for reuse
Experts conducted a test for masks No. 95, which doctors often use.
The researchers conducted an experiment and determined that heating to high temperatures is the best way to disinfect masks.
EurekAlert writes about it.
Following the onset of the COVID-19 pandemic, No. 95 face masks were in short supply. In particular, health workers urgently need these masks for protection when dealing with infected patients. But in the absence of many people have to repeatedly use the same mask. ACS Nano researchers have now tested several methods of disinfecting No. 95 materials and found that heating retains filtration efficiency for 50 disinfection cycles.
No. 95 masks contain a layer of “blown” molten polypropylene fibers that form a porous, breathable network. To help capture smaller particles that can slip through holes, the fibers are electrostatically charged.
The U.S. Centers for Disease Control and Prevention recommended several methods for disinfecting No. 95 masks, such as heating, ultraviolet (UV) radiation and whitening, but so far they have not been thoroughly tested, especially for multiple disinfection cycles. Researchers wanted methods that could reasonably be used in a hospital setting to see how protective materials can withstand repeated disinfection.
