Abstract

Examples of the present disclosure relate generally to absorbing elements in respiratory face masks. In some examples, a structure for respiratory masks that can both absorb moisture from the face (such as perspiration, as well as from condensed moisture in the breath), and maintain a low breath resistance (won't increase the breath resistance significantly) is disclosed herein. The structure includes an annular structure added to the respiratory masks for moisture management. In some examples, the annular structure is made up of moisture absorbent materials. This structure may also be known as an absorbing element operable to absorb moisture effectively, provide a respiratory mask with improved moisture control characteristics, reduce fogging of a face shield or eyeglasses of the wearer, and reduce the amount of uncomfortable moisture buildup on the face of the wearer.
