A cloth face mask is suitable for most people, aside from healthcare workers. Anyone interacting directly with those who have been diagnosed with, or suspected of having, COVID-19, need professional respirators. Otherwise, a cloth mask, either purchased or homemade, will provide protection. A cloth mask isn’t medical-grade, but since we know that the virus causing COVID-19 is transmitted through large respiratory droplets, such as through coughing or sneezing, the cloth covering will help prevent those droplets from getting into your system if you’re out in public. If you’re making your own mask at home or looking for one online, consider cotton over another material, like leather. With a leather mask, air is likely to go around the edges, making it less effective. In general, we should avoid any mask made of material that makes it difficult to breathe while wearing. In a study published by the  American Chemical Society, researchers from the University of Chicago tested the filtration efficiencies of common fabrics, including cotton, silk, and polyester-spandex chiffon. The scientists found that masks made with a combination of fabrics, such as high thread count cotton with two layers of chiffon, were nearly as effective as an N95 medical-grade mask, filtering out 80–99% of particles when tested. At AdventHealth, our medical experts agree that multi-fabric masks can provide the best protection, just ensure they’re being worn correctly and don’t have any gaps around your face.
