Abstract: A half facepiece respirator has a shaped support piece supporting and fixing the position of a particle or paper filter insert or outsert with either the support piece or the particle filter incorporating a face sealing component. Placed within the shaped support piece, a grille may be placed in the lower section of the shaped support piece. Additionally the half facepiece includes a head harness having a release mechanism.

Abstract: A system for monitoring service life of a filter may include a respirator configured to be worn by an individual. The respirator may include a face mask and a filter housing that retains a filter within a filter chamber. A sensor assembly may be configured to monitor gas from the filter chamber. A respirator filter sampling port assembly is configured to adaptively connect the filter housing to the sensor assembly. The respirator filter sampling port assembly may include an adapter that removably secures to the filter housing, and fluidly couples the filter chamber of the filter housing to the sensor assembly.

Abstract: A sensor device is disclosed for providing end of service life indication for an air purification filter. The sensor device has a cylindrical housing for insertion into a sorbent bed of a filter, and can be removed from the bed and reused at the end of the filter service. One or more sensors inside the housing are configured to sense physical/chemical characteristics of air passing through the sorbent bed, and to provide associated data to a sensor conditioning board within the housing. The sensor conditioning board processes the received data and conditions the data as desired. The housing is receivable in a cavity formed in the filter bed. A receiving structure receives the housing therein. Data from the one or more sensors can be used to calculate predicted end of service life of the filter. Other embodiments are described and claimed.

Abstract: A respiratory mask has a filter element that is optimally position relative to the inhale and exhale of a wearer's nose and mouth in relation to the size and shape of the filter allowing a direct pathway of the airflow between the wearer's nose and mouth to the filter. A non-permeable section, incorporated in the filter element, filtering structure, the sealing area or a combination thereof, is used to direct and channel the outer dispersed boundaries of the nasal and oral flow to the filter element. The optimally positioned filter coupled with channeling of the boundary flow through the filter element reduces residency time of exhaled breath in the mask.
