DETROIT – Not all masks are created equal, especially when it comes to preventing the spread of COVID-19. Dr. Kristin Englund from the Cleveland Clinic said it’s important to remember only certain masks are proven effective in reducing coronavirus spread.

Try to find some cloth that matches your costume and make your own masks,” she said. Surgical and cloth masks are often worn to help prevent COVID-19.

DETROIT – Researchers are learning more about what makes a cloth mask more effective against the spread of coronavirus (COVID-19). A new study in the medical journal, Thorax, indicates that layers are essential and that having at least two is better than one layer. Researchers in Australia tested the effectiveness of the CDC recommended one or two layer cloth mask coverings and a three-ply surgical mask. Based on their tests, the researchers said homemade masks should contain multiple layers. Another way to improve a cloth mask is to select one with a pocket that can hold a filter.
