ABSTRACT:
An adjustable mask for supplying a desired atmosphere to the wearer is disclosed. This mask may be either an oxygen mask or a mask for removing dust or pollen. The mask has overlapping upper and lower sections. The area of overlap can be made larger or smaller depending on the facial length of the wearer. The area of overlap is larger for a smaller adult, and smaller for a larger adult. Gripping means, shown herein as snaps and eyelets, are provided on both sections in the area of overlap so that the two sections can be adjustably secured to each other. These gripping means can also consist of velcro or any substance allowing the two mask sections to fit together snugly.
