ABSTRACT:
A lightweight, disposable face mask for covering the entire face of the wearer, which mask comprises a unitary shell of transparent plastic material having upper and lower portions joined at a ridge which traces the facial respiratory line. A band of flexible material is disposed along the ridge and creates an aerodynamic seal between the upper and lower portions of the mask when worn. A strip of soft, flexible material is secured to the mask along the periphery creating a soft, comfortable seal between the mask and the face of the wearer.
