Abstract
An air warming apparatus operable to provide a user breathing air wherein the air is warmer than that of the user's environment. The air warming apparatus includes a filtered air intake operably coupled to an intake manifold. A lower air transport assembly circumferentially surrounds a user's torso and is adjacent thereto and provides the first phase of air warming for air flowing therethrough. A return manifold operably couples the lower air transport assembly and the upper air transport assembly and further contains a humidifier therein. The upper air transport assembly is surroundably mounted to the user and provides the second phase of air warming. An upper chamber of the intake manifold operably couples the upper air transport assembly and the breathing assembly. The breathing assembly includes a mouthpiece and a breathing valve that is operable to control the air flow through the air warming apparatus.
