The recent COVID-19 pandemic has led to widespread use of homemade masks and mask alternatives. It is assumed that wearing such masks reduces the likelihood for an infected person to spread the disease, but many of these mask designs have not been tested in practice. Researchers have designed a simple, inexpensive way to test these masks. The results show the most effective masks are N95's (same effectiveness as KN95's), surgical masks, and poly/cotton masks.
Dr. Anthony Fauci suggested that people wear goggles or face shields as an added measure of protection against contracting the coronavirus.
