ABSTRACT:
A filtering face-piece respirator10that comprises a mask body12and a harness14. The mask body12includes (i) a filtering structure18, (ii) a plastic support structure16, and (iii) a nose clip19that is secured to the plastic support structure18by being molded therein. The inventive filtering face-piece respirator is beneficial in that it eliminates the need for an adhesive or welding step to secure the nose clip to the mask body.
