At least one of the central portion and first and second members are formed from filter media. The device is capable of being folded flat for storage with the first and second members being in at least partial face-to-face contact with a common surface of the central portion and, during use, is capable of forming a cup-shaped air chamber over the nose and mouth of the wearer with the unjoined edges of the central portion and first and second members adapted to contact and be secured to the nose, cheeks and chin of the wearer. The outer boundary of the unjoined edges which are adapted to contact the nose, cheeks and chin of the wearer are less than the perimeter of the device in the flat folded storage state. Also provided are process for preparing such devices.

摘要： A personal respiratory protection device that includes a multi-layered structure and first and second means for attaching a headband. The multilayered structure includes a filter medium and is divided into a flat upper panel, a flat non-rectangular central panel, and a lower panel. The central panel is separated from each of the upper and lower panels by first and second lines of demarcation. The first and second lines of demarcation converge towards the first and second means for attaching a headband. The multi-layered structure can be folded at the respective lines of demarcation so that the device can be folded flat for storage and can be opened to form a cup-shaped off the face air chamber over the nose and mouth of the wearer while an upper peripheral edge and a lower peripheral edge contact the wearer's face when the device is in use.

摘要： A method of making a personal respiratory protection device. The method comprises: (a) forming a multi-layered structure that comprises a first cover web, a filtration layer that comprises a web that contains electrically-charged microfibers, and a second cover web; and (b) adapting the multi-layered structure into a first panel, a central panel, and a second panel such that the central panel is separated from each of the first and second panels by first and second lines of demarcation, and each of the first, second, and central panels is non-pleated. The first and second cover webs are disposed on first and second opposing sides of the filtration layer, respectively, and at least one of the cover webs comprises spunbond fibers. The resulting respiratory protection device is capable of being folded flat at the respective lines of demarcation for storage and can be opened to form a cup-shaped air chamber over the nose and mouth of the wearer when in use.
