According to one embodiment, a custom fitted mask includes a thin sheet of deformable material that has been formed and fitted to a portion of a user's face surrounding the user's nostrils to conform substantially optimally to the user's unique facial features. The portion of the user's face includes only soft cartilaginous portions of the user's nose and portions of the user's face on either side of and below the soft cartilaginous portions of the user's nose. The portion of the user's face excludes hard bony portions of the user's nose generally above the soft cartilaginous portions of the user's nose. According to another embodiment, a mask blank for using in forming a custom fitted mask includes a thin sheet of deformable material adapted to be transitioned from a non-deformable state into a deformable state, applied against at least a portion of a user's face surrounding the user's nostrils while the mask blank is in the deformable state, and deformed against the portion of the user's face to cause the mask blank to conform substantially optimally to the user's unique facial features to form the custom fitted mask.
