  • Patent number: 5782234
    Abstract: An advanced and versatile method for a RESPIRATORY BREATHING FILTER APPARATUS having an outer body that conforms to the natural formation of the human mouth and is engaged by the teeth without the use of hands. Primarily designed for use by users with respiratory ailments, (i.e., asthma, cystic fibrosis, emphysema, allergies related to respiratory problems) the apparatus can be used by users engaged in aerobic activities with safety and fewer body restrictions. The apparatus has an outer body and six removable parts. The first of these parts is a removable outer or macro-particle filter for removal of coarse foreign airborne particles from an incoming airstream. The second of the two filters is separate from the outer filter and is positioned inside the outer body. This second filter is designed to remove smaller or micro-particles from the incoming airstreams. This second filter is removable, which is a tremendous advantage from previously presented methods and systems.
