摘要： A respirator mask seal and shell are provided according to one embodiment of the invention. The respirator mask seal and shell includes a mask shell having a face opening, a slot for air passage, and at least one attachment portion spaced around the face opening. They also include a movable interface having a hose connector and a contoured opening adapted to fit against the mask shell. The contoured opening is slidable over the slot and is capable of being positioned on the mask shell. The mask seal has a flexible sidewall having distal and proximal ends and includes a rounded outer seal portion located on the distal end of the sidewall, a rounded inner seal portion located between the distal and proximal ends, and a support ring embedded in the sidewall. The inner seal portion is thicker than the outer seal portion and is non-continuous. The support ring includes at least one attachment portion adapted to engage the at least one attachment portion of the mask shell. The mask seal is capable of being removably affixed to the mask shell. The movable interface is capable of being positionally adjusted on the mask shell and the mask seal is capable of being inwardly deformed by contact with a face region of the user.
