Abstract
A respiratorthat includes a mask body, a filter cartridge receptacle, and a filter cartridge. The filter cartridgehas a sidethat is capable of being plugged into the receptacle. The filter cartridgecan be inserted into the proper position within the receptaclewhile the mask bodyis being donned. The securement can be achieved without having the user visibly witness the actual engagement. An audible click or other indication can be provided so that the user knows that proper engagement has been achieved. The engagement may exhibit little spacing between the filter cartridgeand the mask body, thereby improving viewer visibility and making the inventive respiratormore comfortable to wear.
