A half-mask covers nose and mouth. A full-face mask adds the eyes and takes the same cartridges in a larger body. The cartridge, not the rubber facepiece, chooses the hazard. The mask has to be the size that seals, which is a fit test, not a guess from a shirt size.
A respirator filters the air the person breathes, or supplies other air. An FFP mask is a particle filter worn on the face.
