A full-face mask including a mask body, a breathing tube, an isolation support portion, and a first partition is provided. The mask body includes a lens portion and a soft portion, the soft portion fits a user's face to form an inner space. The breathing tube is disposed above the mask body and is connecting with the inner space. The isolation support portion is disposed in the inner space to define an upper space and a lower space which are connected with each other. A first partition is disposed in the lower space and includes an intake valve. The lower space is defined with a proximal space and a distal space. When the user inhales, the clean air passes through the intake valve into the proximal space. Thus, the user could effectively breathe, exhale and/or isolated from leakage water to avoid danger.
