Tea towels, cotton wool-blend fabrics and antimicrobial pillowcases were the next most protective items. The more dense the fibers in a mask's material, the better information technology is at filtering. Therefore, higher thread counts atomic number 82 to higher efficacy, Wilson said in the release.
