Cone-style well fitting masks and home-made coverings made from multiple fabric layers are the best designs for stopping the spread of coronavirus, study shows. Researchers from Florida Atlantic University examined different materials and designs to find the best option for slowing the spread of virus carrying droplets. These droplets are expelled when someone with COVID-19 coughs or sneezes and tests show loosely-folded masks and bandana-style coverings perform the worst. According to researchers this is because those designs provide minimal stopping-capability for respiratory droplets which can spread up to 8ft if unobstructed. They found a simple bandana-style mask can stop droplets going more than 3ft but a homemade well-fitting cotton-fabric stitched mask stops droplets at 2.5 inches.
