jbluhm86 Posted April 30, 2020 Report Share Posted April 30, 2020 Military.com: Army Says It Has Found the Best Fabric for DIY Face Masks "...After running about 300 tests, the team found that one of the best readily available materials to use in a homemade face covering is four-ply microfiber cloth, which is popular for cleaning and polishing surfaces, according to the release. "It filters out over 75% of particles," according to the release. "In comparison, the N95 mask used by healthcare workers in hospitals can filter 95 percent of particles or greater." Testers also found that "even a polyester bandana can be reasonably effective if it is used in layers, according to the release, which adds that it will filter out "40 percent of suspended particles." 1 Quote Link to comment Share on other sites More sharing options...
