    摘要: A filtering face-piece respirator that has a harness and a mask body where the mask body includes a filtering structure and a support structure. An exhalation valve is attached to the mask body and includes a valve seat that is integral to the mask body. The present invention is beneficial in that it eliminates the need to separately manufacture some or all of the non-dynamic parts of the exhalation valve. There also is no need to subsequently attach the valve seat to the mask body.
