Abstract
The handheld hair dryer for generating a heated air stream has a blower for generating an air stream, an electric heater for heating the air stream, a catalytic odor filter for deodorizing the air stream and a thermal radiator for heating the catalytic odor filter. The electric heater and the catalytic odor filter are separate from each other so that the active surface area of the catalytic odor filter can be maximized to deodorize the air stream. The thermal radiator is also separate from the electric heater.
