With the increased ability for the omicron variant to spread, many people are wondering if it’s time to up their mask game.

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.
