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.

Cette invention concerne un appareil respiratoire (10) comprenant un élément filtre compressible (12), un logement (14) de l'élément filtre compressible et un élément facial (16). Cet appareil respiratoire se distingue par son élément filtre (12) qui est comprimé lorsqu'il est inséré dans son logement (14), assurant ainsi un assemblage à frottement entre ledit élément filtre (12) et son logement (14). Cet assemblage à frottement permet de remplacer facilement l'élément filtre (12) à la fin de sa durée de vie.
