A face mask is provided having a filter body sized to cover the nose and mouth of a wearer, a securing mechanism for holding the filter body in close fit with the wearer's face, and a fan attachment to enhance breathability and comfort of the mask. The fan is powered and configured with the exterior of the filter body to aid in drawing air through the filter media of the mask. The fan operates to draw warm, moist exhaled air from the interior volume of the mask to improve comfort, facilitate inhalation, and decrease fogging of any transparent portions of the mask or eye coverings. The fan may additionally operate to force cool, fresh air into the interior volume of the mask, also for the comfort of the wearer.
