Abstract
A disposable face mask that includes a filter body capable of filtering liquids and/or particles of a size appropriate for the mask's intended purposes, while providing excellent breathability and comfort to the wearer for extended periods of time. The filter body is formed from multiple layers of filtration material having various configurations. Such masks may be secured by one or more knitted headbands to the head of a wearer. Various gasket-type sealing materials such as plastic film or other materials such as hydrogel may be used to enhance the fluid barrier formed between the periphery of the mask and the wearer's face. For one embodiment the face mask may include a continuous loop of material to secure the mask on a wearer's face.
