A respirator suspension system is disclosed. A face mask for covering the mouth and nasal passages of the user has a peripheral sealing portion for establishing a seal with the user's face and filter cartridges disposed in air inlet passage on either side of the face mask. The cartridges are provided with guide fittings and guide surfaces for support and guiding of a single adjusting strap which interconnects a crown support with the face mask. In accordance with the disclosure, the crown support comprises a first precurved member extending over the top of the head of the user and a second precurved member integrally joined to the first which fits around the back of the head of the user. The elastic strap extends from a juncture portion of the two strap members on one side of the head of the user, around the front of the filter cartridge on said one side of the head of the user, around the back of the neck of the user and then around the other filter cartridge and then through an adjustable strap catch on the juncture member on the other side of the head of the user. A pull on the end of the strap effects adjustment of the respirator into a position in which it seals with the face of the user.
