Will wearing two masks better protect me from the virus? AP Illustration/Peter Hamlin
Does wearing two masks provide more protection?
It depends, but it’s possible that doubling up could help in some situations.
The U.S. Centers for Disease Control and Prevention recommends wearing a cloth mask made with two or more layers, and ensuring it covers your nose and mouth. The agency says it should fit snugly so there aren't any gaps at the sides of your face.
Wearing just one mask should be enough for most situations, as long as it fits well and isn't loose, said Dr. David Hamer, an infectious disease expert at Boston University.
“Starting out with a good mask to begin with is going to be key,” Hamer said.
Still, some people might want extra protection if they're at risk for severe illness if infected or will be in situations where they expect to be around others for extended periods, such as on a plane.
One option in scenarios when you want extra protection is to wear a cloth mask as well as a regular surgical mask, said Dr. Monica Gandhi, an infectious disease expert at the University of California, San Francisco.
Gandhi said that combination -- with either mask on top -- could help achieve a similar effect as the N95 mask. She recommended the added protection for people who will be indoors in areas where transmission rates are high — which could reflect the circulation of more contagious variants.
Another option Gandhi and a colleague recommend for situations where you want “maximum” protection: A two-layer cloth mask that has a filter material in between.
With single cloth masks for everyday use, Gandhi noted it's important that they're made of tightly-woven material and have at least two layers, which creates “an obstacle course” that makes it harder for virus-carrying particles to break through.
Stan Farnsworth, chief marketing officer at PulseForge, joined Cheddar to talk about his company's debut at CES 2022 and how it plans to innovate the sustainable tech manufacturing space. PulseForge is bringing a new approach to industrial thermal processing, which contributes to 30 percent of global greenhouse gas emissions, according to Farnsworth. "By using 85 percent less energy in the processing of materials through a variety of manufacturing processes, we can make a direct impact in reducing carbon output and reducing carbon footprint associated with manufacturing," he said.
The U.S. will be implementing a vaccine mandate for all people entering through its land borders, removing exemptions for "essential" travelers such as truckers, students, and business people. While the Canadian Trucking Alliance argues that the new, stricter rule might exacerbate ongoing auto supply chain issues, some health experts see the potential for helping curb the ongoing pandemic. Anthony Santella, a professor of health administration at the University of New Haven, joined Cheddar to give his take on the updated border crossing restriction. "We can't just focus on one type of travel. We need to ensure that it's clear and consistent across all types of travel," Santella said.
