This is a brief note to point you to the news story and research article.
The best mask is an N95 medical mask (the 3M blue masks without valve). The mask that is most realistically obtainable by the general population is a homemade mask made of quilter’s cotton, double layer with a polypropylene filter in the filter pocket. The polypropylene (PP) that is most available are the blue shop towels. Please also reference Suay’s findings.
None of this news should be “new” to my readers. I just wanted to give you some additional resources to consider. Please see my previous posts/coverage.
