A slide-on, slide-off frame is disclosed that carries a medical face mask of the kind to be worn by healthcare providers and others who wish to avoid contracting or spreading an infectious disease, such as the coronavirus known as COVID-19. The frame includes a bridge to which the face mask is attached. A pair of L-shaped ear engaging arms stand upwardly from opposite ends of the bridge to lie on top of the wearer's ears to hold the frame on the wearer's face. In one embodiment, the upstanding ear engaging arms are rotatable downwardly into the plane of the bridge so that the frame can be carried in a purse or hand bag. In another embodiment, the frame is manufactured from a single continuous piece of material, such that the face mask is slidable off the bridge and removed from the frame.
