UMass Amherst Air Quality Researchers Tested Mask Effectiveness

Caption

Richard Peltier, Kabindra Shakya and colleagues believe theirs is the first study to rigorously test disposable surgical masks and washable cloth masks, widely used in Asia and Southeast Asia for personal protection against airborne particulate matter. They found that cloth masks reduced exposure somewhat, but 'the most commonly used cloth mask products perform poorly when compared to alternative options available on the market.'
