A respirator (10) that includes a mask body (12) and at least one filter cartridge (24). The mask body (12) has a central portion (14) and a peripheral portion (16). The filter cartridge (24) is attached to the rigid central portion (16). The peripheral portion 14 is made from a low stiffness first thermoplastic material, and the central portion (16) is made from a rigid second thermoplastic material.

A respirator of this structure can be made in a convenient manner, with a sound hermetic bond between the parts, while also being light in weight.
