ABSTRACT:
A cold weather breathing device which heats and humidifies air to be breathed. A face mask which covers the mouth and nose includes intake and exhaust ports each equipped with a one way valve. An open sided conduit which is U-shaped in section extends in opposite directions from the mask along opposite sides of the head. A corrugated metal partition divides the conduit into side by side intake and exhaust passages. The intake passage is adjacent the open side of the conduit so that incoming air flowing through the intake passage is directly heated and humidified by the face, head and neck. The heat from the exhaled air in the exhaust passage is also transferred to the incoming air through the partition.
