Abstract
A mask insert to provide conformal support for the reflective seal of an oxygen mask comprising a formed rim made of a resiliently deformable material which is held in place beneath the reflective seal by a supporting framework which conforms to the contours of the interior surface of the mask. The formed rim applies constant pressure on the face-engaging surface of the reflective seal, adjusting for variations in the user's facial structure, thereby eliminating leaks.
