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.

[Problem] In a conventional protective garment, the internal environment of a garment body becomes worse due to the wearer’s exhaled breath, and therefore the wearer suffers from the difficulty of having to perform work for a long time under unpleasant conditions. [Solution] This protective garment, which is used to protect a human body against foreign substances, comprises a garment body that covers at least a portion of the human body, wherein a fan that supplies external air to the inside of the garment body is embedded in the garment body, the fan comprises a filter for filtering the external air supplied to the garment body by the fan, and thus the protective garment, which suppresses a deterioration of the internal environment of the garment body, so that work can be performed for a long time under pleasant conditions, can be provided.
