"A study of health-care workers in more than 1,600 hospitals showed that cloth masks only filtered out 3 percent of particles. An article in the New England Journal of Medicine stated, "[W]earing a mask outside health care facilities offers little, if any, protection from infection" and that "[T]he desire for widespread masking is a reflexive reaction to anxiety over the pandemic."
There are many other credible studies showing lack of mask efficacy, such as studies published in the National Center for Biotechnology Information, Cambridge University Press, Oxford Clinical Infectious Diseases, and Influenza Journal, just to name a few.
