Abstract: Provided are face coverings that include a cover panel made from a cover panel material, a filter made from a filtration media adjacent the cover panel, and a retaining system for securing the face covering to a wearer's face. The face coverings can further include a gasket comprising gasket material connected to a perimeter of the cover panel and configured to contact to a wearer's face. The pressure drop across a combination of the cover panel material and the filtration media is from 45% to 75% of the pressure drop across the gasket material, enabling filtration of airborne contaminants allowing for reduced retaining tension and improved comfort to the wearer.
