There are however a number of FDA hoops that manufacturers can jump through to indicate some degree of quality and performance. The goal of this post […]
A huge thank you to everyone that has contributed to our fabric mask material testing campaign! The results from the testing campaign are finally in. We tested two different 3-layer fabric combinations to establish baseline performance for fluid resistance, breathability, bacterial filtration efficiency (~3um particles), and submicron particle efficiency (~0.3um). These tests focused on two […]
Since February of 2020, we’ve been asking for standards for masks/face coverings used by our communities. Finally, the American Society for Testing and Materials (ASTM) has established a national standard for “Barrier Face Coverings” (ASTM F3502) that are neither medical masks according to ASTM F2100 standards nor respirators according to NIOSH standards. This new standard […]
