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, 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 five removable component parts. The outer body contains an outer or frontal filter for removal of coarse foreign airborne or macro-particles in an incoming airstream. The second of the filters, separate from the outer filter in the outer body, is designed to remove smaller or micro-particles from the incoming airstream. This second filter is easily removed, which is a tremendous advantage from previously presented methods and systems. A medicament with minimal dosage is evaporatively added to the incoming airstream and provides aided relief to the user having respiratory tract ailments. A removable retaining ring maintains the second filter and medicament in place during use. Two one-way valves open during exhalation and close during inhalation. Method of use is also disclosed.
