The new study in Risk Analysis suggests that the effectiveness of cloth masks can be improved by using a non-woven material such as cotton batting. Increasing the surface area of fibers exposed to moving air improves filtering efficiency because the smaller particles are absorbed onto the fibers. ...
A team of researchers studying the effectiveness of different types of face masks has found that in order to provide the best protection against COVID-19, the fit of a mask is as important, or more important, than the material it is made of. The researchers, from the University of Cambrid...

The effectiveness of face masks has been a hotly debated topic since the emergence of COVID-19. However, a new study by researchers at the University of Central Florida offers more evidence that they work. In a study appearing today in theJournal of Infectious Diseases, the researchers found ...
could share with others in the community to encourage the testing of materials, masks prototypes and fittings,” explains Fischer. “The parts for the test apparatus are accessible and easy to assemble, and we’ve shown that they can provide helpful information about t...
Mask-wearing during the COVID-19 pandemic has prompted a growing interest in the functional impact of masks on speech and communication. Prior work has shown that masks dampen sound, impede visual communication cues, and reduce intelligibility. However,
"Face masks or respirators (N95/KN95) have been shown to help filter out virus particles in laboratory conditions. This study builds upon data from laboratory settings and demonstrates the real-world effectiveness of wearing masks to protect the wearer from COVID-19," the California Department of...
based on symptom reporting and SARS-CoV-2 antibody testing. The team tested both cloth and surgical masks and found especially strong evidence that surgical masks are effective in preventing COVID-19. In the study, surgical masks prevented one in three symptomatic infections among community members...
-19 pandemic. Mechanical science and engineering professor Taher Saif spoke with News Bureau physical sciences editor Lois Yoksoulian about a study that he and his graduate students, Onur Aydin and Bashar Emon, performed on the effectiveness of common household fabrics for use in homemade masks....
Local mechanical engineers say more research is needed regarding which masks are effective in preventing droplets from reaching others.
