The invention relates to a deodorization and sterilization nanometer propolis filter for an automobile air conditioner. The deodorization and sterilization nanometer propolis filter for the automobile air conditioner is composed of an upper cover and a lower cover; and raw materials of a nanometer propolis composition in weight are as follows: nanometer propolis, nano silver, clove oil and forsythia oil. The invention breaks through the worldwide problems that the PM2.5 removal rate of automobile air conditioner filter screens at home and abroad is low, bacteria or viruses can not be killed, peculiar smell can not be removed, and secondary pollution is produced. The filter provided by the invention has the keys that high-efficiency PM2.5 purification, rapid decomposition of toxic and harmful odor, powerful killing of the bacteria and viruses and no blockage during filtration are solved, the peculiar smell is rapidly eliminated, no secondary pollution is produced, and creativity that a bump channel frame can be recycled is realized; no usage of filter screens, large air flow, small size and low weight are realized, so that the filter can be conveniently used on various automobile air conditioners, multiple appearance shapes can be matched with various automobile air conditioners in application, and an integrated structure is adopted; and the filter is durable and flexible to dismount and replace, clean air in a compartment is really realized, the manufacturing cost is low, public users can afford the filter, and the filter provided by the invention has practicability.
