Abstract: A respirator is described that includes a mask body and at least one housing directly or indirectly coupled to the mask body. The at least one housing includes a pair of slots spaced apart from each other, a cantilevered snap feature disposed between the pair of slots, and a latch connected to the cantilevered snap feature. The respirator further includes at least one cover movably coupled to the at least one housing and including a pair of arms. Each of the pair of arms is disposed adjacent to a corresponding slot from the pair of slots and includes a wide end portion. The at least one cover further includes an elongate member extending between the pair of arms and connected to the wide end portion of each of the pair of arms. The elongate member is at least partially received through each of the pair of slots.
