Abstract
A frigid air respirator comprising a cylindrical housing affixed to a face mask, openly constructed so as to permit the passage of air upon inhalation by the user into the chamber formed by the housing. A heating means is situated within the housing to increase the temperature of incoming air by radiation and a transversely positioned intake valve governs the admission of air into the respiratory tract of the user and divides the chamber formed by the housing into an internal chamber which is contiguous with the mask cavity and into a receiving chamber wherein a supply of previously heated air is stored prior to inhalation. An exhaust valve is encompassed into the device to allow the expulsion of air from the internal chamber and mask cavity.
