Title: Informing Homemade Emergency Facemask Design: The Ability of Common Fabrics to Filter Ultrafine Particles Document date: 2020_4_17
ID: 51thatw6_5
Snippet: This study aims to address the paucity of information regarding materials for face mask construction by evaluating the efficiency of twenty widely available fabrics and materials, particularly those available to the general public in filtering particles smaller than 0.1 μm (100 nm). Both individual materials and material combinations were tested with the goal of increasing particle filtration of homemade masks. In addition, materials which could.....
Document: This study aims to address the paucity of information regarding materials for face mask construction by evaluating the efficiency of twenty widely available fabrics and materials, particularly those available to the general public in filtering particles smaller than 0.1 μm (100 nm). Both individual materials and material combinations were tested with the goal of increasing particle filtration of homemade masks. In addition, materials which could be washed and dried in very hot water were preferred for their efficacy ameliorating the risk of infection in two particular situations: (1) infection due to the reusing of masks, and (2) reduction of filtration efficacy due to moisture buildup.
