摘要： A respirator (10) includes a compressible filter element (12), a filter element retainer (14), and a face piece (16). The respirator is unique in that the filter element (12) compresses when installed in the retainer (14), allowing a friction fit to be maintained between the filter element (12) and retainer (14). The friction fit enables the filter element (12) to be readily replaced when its service life has expired.
