If double-masking is hurting your ears, try these tips to relieve the pain “In general, of the many masks that we tested — and there are over 50 — the ones that seemed to provide the best fit were the ones that had elastic that went around the back of the head and the back of the neck,” Fernandez said.

Here’s what the experts say In another study, Dr. Loretta Fernandez, an associate professor at Northeastern University, found that adding a layer of nylon to a homemade mask can make it fit more snugly over the nose and mouth. 5 Hacks To Make Your Face Mask More Protective Then pull the ring over your head and on top of your mask to create a tight fit to the face. Tights should also work well, says Loretta Fernandez, an assistant professor of civil and environmental engineering at Northeastern University who conducted prior research on the power of pantyhose. Are two masks better than one? Double masking ‘just makes common sense’ to help prevent COVID-19 spread, Fauci says A study published in the peer-reviewed journal Matter in July found that wearing two masks could increase protection from virus particles by 50% up to 75%. It not only added an extra layer of protection but also made the mask fit snugger around the face, said Dr. Loretta Fernandez, study author and associate professor at Northeastern University. Coronavirus FAQs: Are 3 Masks Better Than 1? Will Mouthwash Keep You Safe? As correspondent Maria Godoy reported: Researchers at Northeastern University added an outer layer made from nylon stockings to a homemade face covering. They found that the nylon layer can boost a mask’s ability to filter out small particles in the air by creating a tighter seal between the mask and the wearer’s face. How to Choose the Best Cloth Face Mask for You A recent Northeastern University paper (PDF) reports that a surgical mask sealed to the wearer with a band cut from a pair of nylon stockings went from blocking out 50% to 75% of small particles (less than 0.3 micron) to blocking 90%. “The fit was already good,” said study co-author Loretta Fernandez, an associate professor of civil […] The Telegraph Do face masks work? Here’s what the science says Laboratory testing by Northeastern University, in Boston, found that surgical masks block out 75 per cent of respiratory-droplet-size particles, while the University of Hong Kong found that loose-fitting surgical masks block almost all contagious droplets breathed out by infectious people. Want To Create A Better Mask? It’s Harder Than It Seams We asked researchers Loretta Fernandez and Amy Mueller at Northeastern University to test the Bilio mask. They’ve been testing the performance of a range of various masks, measuring to see how well they protect the wearer from inhaling particles that may carry the coronavirus.

Face masks help prevent you from spreading the coronavirus. But can they prevent you from catching it? Face masks help prevent you from spreading the coronavirus. But can they prevent you from catching it? The scientific evidence is growing about the importance of masks in fighting COVID-19. But one important question is whether homemade masks can protect people wearing them. The answer depends on the fit of a mask and the materials within it, research by Northeastern engineers suggests.
