ABSTRACT:
A multipurpose face mask made of supple material covers the nose, mouth, and chin with a two sided chamber held away from the entrance of the nostrils and the mouth by a rigid support attached inside the vertical front fold. This rigid support makes possible the use of a wide variety of soft materials in one or more layers, which may serve to filter dust, pollen, mold, dander, powder, and other common airborne particles, and/or to warm and humidify cold, dry air. For versatility in purpose, a disposable version may fit inside a reusable version. The cold weather version may have air holes in the outer layer. This device of supple material can be made in several sizes and rolled to fit in a pocket or purse and has an attractive, lean appearance with potential for embellishment. This invention in its many forms enhances the lives of people with respiratory disorders or professions which require respiratory protection.
