Face Mask

Description

What are the best materials for cloth face masks?

Based on our summary of 25 different studies, woven cotton, at least 100 threads per inch; flannel, either cotton or poly-cotton blend, at least 90 threads per inch; tea towel material; and heavy, good quality, cotton T-shirt material all performed well. This recommendation is based on the published data available, which doesn’t cover all possible mask materials: we didn’t find a lot of information on synthetic materials, for example, so we don’t know how they compare.
