A respirator comprising a facepiece having a cup shaped portion for sealingly engaging a face of a wearer and covering the mouth and nose of the wearer and a cover having a cup shape that is complementary to the cup shaped portion of the facepiece. The cover is capable to detachably mate with the facepiece to define with the facepiece a void area that is cup-shaped and suitable to receive a filter having a complementary shape. The filter includes an apex portion, a side portion depending from the apex portion and a continuous flange portion surrounding said side portion and projecting laterally therefrom.

La présente invention concerne un masque filtrant comprenant une jupe de masque, qui présente une partie cupuliforme, conçue pour s'adapter de manière hermétique sur le visage d'un porteur et pour protéger la bouche et le nez du porteur, ainsi qu'un couvercle cupuliforme, qui est complémentaire de la partie cupuliforme de la jupe de masque. Ce couvercle peut s'associer de manière amovible à la jupe de masque afin de définir un espace vide cupuliforme pouvant recevoir un filtre de forme complémentaire. Ce filtre présente une partie de sommet, une partie latérale, qui dépend de cette partie de sommet, ainsi qu'une partie de rebord continue, qui entoure ladite partie latérale et fait latéralement saillie de celle-ci.
