Abstract
A face mask includes a valve protector between a strap and an exhalation valve thereof. The valve protector's thickness defines a spacing between the strap and a strap retainer that is positioned on a mask body, disposed over the exhalation valve, and receives the strap. This spacing controls an extent of friction between the strap and the strap retainer.
