Patent number: 8794238Abstract: A filtering face-piece respirator 10 that comprises a mask body 12 and a harness 14 that is joined to the mask body 12. The mask body 12 includes a filter layer 30 and a nonwoven fibrous cover web 16. The fibrous cover web 16 is partially occluded and is generally parallel to and spaced from the filter layer 30 such that air passing through the cover web 16 can move freely between the cover web 16 and the filter layer 30 so that it can enter the filter layer 30 at essentially any available point over the filter layer surface 32. The inventive respirator is beneficial in that it can provide very good splash fluid and airborne contaminant protection while also exhibiting an extraordinary low pressure drop across the mask body during breathing.Type: GrantFiled: December 28, 2010Date of Patent: August 5, 2014Assignee: 3M Innovative Properties CompanyInventors: Nhat Ha T.
