    摘要： A respirator that has a mask body and a nose foam, the mask body being adapted to fit over the nose and mouth of a person and having an interior surface that curves concave downward in the nose region of the mask body. The nose foam has first and second opposing major surfaces and a thickness T that extends from the first major surface to the second major surface. The first major surface of the nose foam is secured to the interior surface of the mask body in the nose region, and the opposing second major surface of the nose foam is available for making substantial contact with a person's nose when the mask body is placed on a person's face. At least the first major surface of the nose foam has a predefined downward concave curvature. A nose foam that is pre-shaped in this manner has less opportunity to become pinched or unnecessarily deformed before being placed on a wearer's face.

    摘要： A respirator 10 that has a mask body 14 and a malleable nose clip 12. The mask body 14 is adapted to fit at least over the nose and mouth of a person to define an interior gas space that is separate from the exterior gas space. The mask body 14 has the nose clip 12 secured to it and can include at least one layer of filter media 20. The malleable nose clip 12 comprises a semi-crystalline polymeric material that has an integrated diffraction intensity ratio of at least about 2.0. The nose clip 12 can be deformed into a desired configuration that enables the mask body 14 to maintain a snug fit over a person's nose when the respirator is worn for extended time periods. Because the nose clip 12 does not need to contain metal, the whole respirator 10 can be easily processed as waste in an incinerator when its service has ended.
