Abstract:
A filtering face-piece respirator 10 that comprises a mask body 12 and a harness 14. The mask body 12 includes (i) a filtering structure 18, (ii) a plastic support structure 16, and (iii) a nose clip 19 that is secured to the plastic support structure 18 by 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.
