A filtering face maskthat has a harnessand a mask body. The mask bodyincludes a filtering structureand a cup-shaped shaping layerwhere the latter comprises a closed cell foam layer that has a plurality of fluid permeable openingslocated in it. The openingsare surrounded by recessed regions. The filtering structuredoes not make substantial contact with the shaping layerat the recessed regions. The shaping layermakes contact with the wearer's face at the mask body perimeterwhen the respirator is being worn. The use of a foam shaping layer that has openings surrounded by recessed regions provides sufficient structural integrity or stiffness to prevent mask body collapse during respirator use while also exhibiting a low pressure drop and rapid fluid distribution of air within the mask to allow for low breathing resistance and extended wearer comfort.
