As we continue our fight against the coronavirus pandemic, the Centers for
Disease Control and Prevention recommend wearing a face mask in public while
shopping for essential items. It is especially advisable for people living in areas
hit hard by the spread of the COVID-19 disease. But there’s one thing many of us
don’t realize: Washing face masks is as important as wearing them.
Ever since the global pandemic hit us, researchers have been studying how long
it can live on various surfaces. A new report published in The Lancet says the
infectious virus could still be present on the outer layer of a mask for up to seven
days.
“Strikingly, a detectable level of the infectious virus could still be present on the
outer layer of a surgical mask on Day Seven,” the researchers wrote. They also concluded that various disinfectants can be used to kill the novel coronavirus to clean the mask properly. We reached out to some experts to find out how to effectively wash face masks.

Is your mask susceptible to the virus?
Homemade masks are definitely susceptible to viruses. Wearing a mask reduces
the concentration of virus particles that can be inhaled from respiratory droplets,
which in turn reduces the transmission of COVID-19, but masks can also carry
the virus.
“Cotton cloth is not designed to fully filter virus particles in the nanometer range. However, it could be very helpful for asymptomatic individuals who would normally be wearing nothing,” said Rodney Rohde, associate dean for research at the College of Health Professions at Texas State University. Dimitar Marinov, assistant professor in the department of hygiene at the Medical University of Varna, told HuffPost that up to 97% of the air’s virus particles can easily penetrate cloth masks. “This is why we advise the use of cloth masks as a method to protect others but not for self-protection,” he added.
How often should we wash our masks? The C.D.C. recommends washing your mask at least once a day. “It should be washed typically when you are done with it,” Rhode said.
Robert Amler, dean of the School of Health Sciences and Practice at New York Medical College and a former C.D.C. chief medical officer, suggested washing your fabric mask after every use. “Avoid touching your face and wash your hands before and after,” he said.
Emily de Golian, a board-certified dermatologist at Dermatology Consultants in
Georgia, told us that, ideally, masks shouldn’t be worn for more than 30 minutes
because the dampness from our breath makes it less effective as a barrier against
coronavirus transmission.
If you’re a frontline worker or spend your time in public where social distancing
measures are difficult to maintain, consider washing your fabric mask every two
hours, if possible, Marinov advised. What’s the best way to wash and dry a fabric face
mask? It is important to note that detergents with bleach-like compounds or other
active ingredients should be used when washing masks. Those kill microbes
more effectively than standard detergents, Rhodes explained.
Machine washing is optimal, and the material of your face mask will determine
the temperature of the water. “Fabric masks can be washed in the warmest
possible water that the fabric will tolerate,” de Golian said. Marinov advised keeping the World Health Organization’s specifications in mind. “The temperature should be at least 60 degrees Celsius [140 degrees Fahrenheit]. We do not have studies on SARS-CoV-2, but the similar SARS-CoV1 dies quickly at temperatures above 60,” he said.
You can also disinfect masks by ironing or putting them in an oven for 20 minutes at about 160 degrees Fahrenheit, Marinov said. If hand washing is your only option, de Golian suggested lathering the masks with soap and scrubbing them for at least 20 seconds with warm to hot water. “Washing should be followed by hot air drying,” Almer said.
Dry your mask on the highest possible heat the fabric will allow. Again, this will
depend on what material was used to construct your mask.
