More Information
Summary:The present disclosure provides a face cover comprising a cover panel made of a cover panel material, a filter made of a filter media adjacent the cover panel, and a retention system for securing the face cover to a face of a wearer. The face cover may further include a gasket including a gasket material, the gasket connected to a perimeter of the cover panel and configured to contact a face of a wearer. The pressure drop across the combination of the cover panel material and the filter media is from 45% to 75% of the pressure drop across the gasket material, enabling airborne contaminants to be filtered, allowing for reduced retention tension and improved wearer comfort. 本公开提供了面部覆盖物，包括由覆盖面板材料制成的覆盖面板、与该覆盖面板相邻的由过滤介质制成的过滤器、以及用于将该面部覆盖物紧固到佩戴者的面部的保持系统。该面部覆盖物可进一步包括垫圈，该垫圈包含垫圈材料，该垫圈连接到该覆盖面板的周边并且被构造为接触佩戴者的面部。跨该覆盖面板材料和该过滤介质的组合的压降是跨该垫圈材料的压降的45％至75％，使得能够过滤空气传播的污染物，从而允许减小的保持张力和改善的佩戴者舒适度。
