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.
