Abstract: A frame is configured to improve the seal of a face mask worn on the face of a human. The frame generally includes one or more flexible pieces that conform to the human wearer's face. The frame compresses the face mask against the face of the human wearer. In some embodiments, the frame includes a nose section that conforms to the human's nose, a pair of cheek sections each extending laterally away from the nose section and across the human's cheek bones and downward toward the human's mandible, a plurality of strap anchors on the cheek sections, and one or more straps connected to the strap anchors on the cheek sections. The frame may also include a chin section that is unitary with the cheek sections, or a separate chin strap that is connected to the cheek sections with elastomeric bands.
