Abstract: A full-cover face filter mask includes a mask body presenting the outline of the face of the human body and having a cavity large enough to accommodate the face of the human body and an air inlet and an air outlet in communication with the cavity, and a splice frame made of a soft material and set to the mask body along the edge of the cavity. When the mask body is placed on the face of the human body, the face of the human body is fully contained in the cavity and the splice frame closely fits around the face of the human body, so that the mask body isolates the human body face and the external environment to prohibit the external air pollutants, viruses, etc. from touching the human face, avoiding infection of the human body and preventing disease.
