A photocatalyst device including: a body; a light source part fixed to the body to irradiate ultraviolet light and having an LED and a substrate for fixing the LED thereto; a catalyst part fixed to the body to conduct photocatalytic reaction with the light irradiated by the light source part and thus to generate superoxygen radicals; and a heat radiating part disposed on the light source part to radiate the heat generated from the light source part, whereby the photocatalyst device purifies air and sterilizes and deodorizes the evaporator, while being easily mountable as a single module.

An air cleaning apparatus mounted to an internal automobile structure selected from an armrest, a console, a seat, a headrest, an overhead console, a handle, and a door, includes an air inflow unit arranged in the internal automobile structure, through which air inside an automobile is introduced, an air cleaning unit which is arranged in the internal vehicle structure and filters the introduced air inside the automobile, a first air flow path arranged in the internal automobile structure, through which the air, having been introduced through the air inflow unit and filtered by the air cleaning unit, is discharged to the interior of the automobile, and a second air flow path arranged in the internal automobile structure, through which blowing air, having been introduced to the internal automobile structure and not having passed through the air cleaning unit, is discharged to the interior of the automobile.

An air pollution reacting system in a vehicle comprises at least one air pollution measuring device installed in a vehicle and configured to measure an air pollution level of ambient air; and an air pollution reacting device configured to take at least one action in response to an air pollution level determined by the air pollution measuring device.

According to the invention, there is provided a positive pressure vent for a vehicle. The vent includes an inlet chamber having an air intake port facing into an air stream generated by motion of the vehicle so as to collect air and form a positive pressure inside the inlet chamber. There is further provided a filter adapted to filter air from the inlet chamber of particulate matter. A filtered air path is further provided for allowing filtered air from the filter to travel to the interior of the vehicle under the urging of the positive pressure from the inlet chamber.

A flat filter element for filtering a fluid may include a filter body made up of a folded filter material. The filter element may also include a circumferential edge and a side edge running in a circumferential direction along the circumferential edge. The side edge may have at least one strip portion, running along the side edge, with a side strip that may be separate from the filter body and arranged on the filter body. The side edge may also have at least one adhesive portion running along the side edge for sealing the filter body. The at least one adhesive portion may be formed by gluing of least two folds, adjacent along the side edge, in a region of the side edge.

The present invention relates to a vehicle air conditioner device, comprising: an air purifying unit for regulating air quality inside the vehicle; an inside air quality acquiring unit for acquiring air quality inside the vehicle; an outside air quality acquiring unit for acquiring air quality outside the vehicle; and a display unit for displaying information related to the acquired air quality inside the vehicle and information related to the acquired air quality outside the vehicle.
