Abstract: A filtering face mask 10 that has a harness 14 and a mask body 12. The mask body 12 includes a filtering structure 18 and a cup-shaped shaping layer 20 where the latter comprises a closed cell foam layer that has a plurality of fluid permeable openings 22 located in it. The openings 22 are surrounded by recessed regions 31. The filtering structure 18 does not make substantial contact with the shaping layer 20 at the recessed regions. The shaping layer 20 makes contact with the wearer's face at the mask body perimeter 19 when 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.
