Electronic air cleaner for passenger compartment of vehicle

In a vehicle having an electric device sensitive to electric noise and having an electric air cleaner for cleaning air in a passenger compartment, said cleaner being positioned close to the electrically sensitive device and comprising an electrostatic precipitator for removing fine dust particles suspended in the air, said precipitator including electrically insulated first and second groups of electrodes between which a high electric potential is applied;

• an ultraviolet lamp for sterilizing the air;
• a deodorizing filter for eliminating smell in air;
• a holder by which said deodorizing filter is supported;
• and at least one lead wire which extends along said deodorizing filter from an electric power source to said ultraviolet lamp for providing said lamp with electric power, said lead wire having a tendency to radiate electrical noise;
• an improvement for reducing the effect of electrical noise generated by said lead wire, wherein said deodorizing filter has a frame and said holder has wall portions defining a channel, a part of said frame being snugly seated in said channel to form an enclosed space bounded by said wall portions, said enclosed space receiving therein said lead wire, and said wall portions being constructed of an electrically conductive material to conduct to ground electrical noise generated by said lead wire.
