PURPOSE: An air conditioner filter structure for a vehicle is provided to confirm an appropriate time for exchanging a filter with the naked eye, thereby preventing lowering of blowoff force and an odor due to a contaminant. CONSTITUTION: A filter cartridge(10) includes a filter paper(14) formed in a plurality of layers inside a case(12). A light source(20) is installed inside the filter paper for applying light to one side of the case. In the case that a contaminant is deposited at the filter paper and a contamination state of the filter paper gets to a predetermined set state, the light source is installed at a position cutting off the light emitted to the case. A display unit(30) is installed at the case for transmitting the light emitted from the light source to confirm with the naked eye.
