A treatment fitting is disposed on the body and is coupleable to a treatment source such that a seal in the treatment fitting transitions from a closed state to an open state to allow fluidic communication between the treatment source and the treatment passage. The device configured to permit (i) inhalation air and/or exhaled breath to be drawn and/or expelled through the filter fitting, the respiration passage, and the mask fitting and (ii) a respiratory therapeutic to be drawn from the treatment source coupled to the treatment fitting, through the treatment passage, and through the mask fitting.
