Dr. Anthony Fauci is now recommending that people wear two masks at once to combat the spread of the coronavirus.
Fauci, who remains the face of the federal government’s effort to combat the spread of the coronavirus, says two masks provide better filtration than just one mask.
As Fox News reports, Fauci said the combo should include one tightly woven mask with one surgical mask.
“If you have a physical covering with one layer, you put another layer on, it just makes common sense that it likely would be more effective,” he said during an interview on the TODAY show.
“That’s the reason why you see people either double masking or doing a version of an N95,” he added via the report.
As for the data, the Center for Disease Control and Prevention confirms wearing two masks has “demonstrated superior performance” to just wearing a single layer.
“Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts,” the CDC said late last year.
The recommendation also seeks to provide more immediate coverage to people who have been wearing homemade face coverings, which researchers found provided “as little as 1 percent filtration.” This is compared to an N95 medical mask which provides 97 percent filtration.
Here’s more, per Fox News:
Researchers at the Wake Forest Baptist Medical Center evaluated approximately 400 masks made by community volunteers in order to find which, if any, masks worked as well as N95 respirators or any other medical-grade surgical masks.
According to the study, the best design was that of a double-layer mask made of heavyweight “quilter’s cotton,” consisting of a thread count of 180 or more.
The inferior masks consisted of single-layer or double-layer designs made of lightweight cotton.

One study published in the medical journal Cell on Dec. 15, 2020 found that either wearing a cloth mask on top of a surgical mask or wearing a triple layer mask consisting of varying fabrics can filter up to 90% of particles.
