A flat-fold, filtering, face-piece respirator that has a harness, a mask body, and first and second flanges. The mask body is capable of being folded flat for storage and can be opened into a cup-shaped configuration for use. The mask body has a filtering structure and has the first and second flanges disposed on first and second mask body sides. The first and second flanges project both laterally x and frontally y from the mask body. The provision of the flanges on each side of the respirator is beneficial to ease of mask donning, doffing, and adjustment, and to face fit and maintaining the open shape or configuration of the mask body.

The present disclosure generally relates to display systems, display devices, and methods of making and using them. Some exemplary display systems are capable of attaching a display device to a computer monitor. The exemplary display systems sought to create improved display systems and devices capable of displaying information to a user and attaching to a computer monitor and/or large format electronic display.

A flat-fold filtering face piece respiratorthat comprises a mask bodythat has a transversely-extending line of demarcationand a longitudinal axis. First and second weld patternsare disposed above and not traversing the line of demarcation on each side of the longitudinal axis, respectively. Third and fourth weld patternsare disposed below and not crossing the line of demarcationon each side of the longitudinal axis, respectively. Each of the first, second, third, and fourth weld patterns-is a two-dimensional enclosed pattern. This combined weld patterns can provide a mask body that exhibits crush resistance without the need for additional or heavier layers, which may cause higher pressure drops across the filtering structure.
