PURPOSE: Provided is an automobile antibacterial filter using silver chemical compound and zeolite as a catalyst, the filter having semipermanent antibacterial and deodorizing characteristics. CONSTITUTION: The filter is manufactured by performing the steps of (a) fusing silver 100g, (b) dissolving the fused silver 100g into nitric acid 200ml, (c) dissolving alum 30g into water 100ml, (d) mixing the solutions of the steps (b) and (c), thereby obtaining silver solution (e), feeding caustic soda into the silver solution of the step (d), (f) boiling the silver solution of the step (e), thereby obtaining silver powder, (g) preparing catalyst solution by dissolving palladium chloride 1g, stannous chloride 50g, citric acid soda 50g and hydrochloric acid 100ml into water 500ml, and boiling the complex solution to vaporize chlorine, (h) dissolving the silver powder of the step (f) into the catalyst solution of the step (g), thereby obtaining silver colloid which is an antibacterial agent, (i) preparing deodorizing agent by dissolving aluminum powder 150g and sodium silicate 200g into caustic soda 500ml, and mixing the caustic soda 500ml with water 200ml, (j) dipping a filter into the antibacterial agent of the step (h), (k) dipping the filter of the step (j) into the deodorizing agent of the step (i), and drying the filter of the step (k).
