[0019] Embodiment: An automobile air conditioner filter that is convenient for installation and replacement.

[0020] Refer to Figures 1 to 5 As shown, an automobile air conditioner filter that is convenient for installation and replacement includes: an outer frame 1, the outer frame 1 includes a frame body 11, the center of the frame body 11 is separated into two independent filter element installation cavities by a partition board 12, and an air filter element 2 is installed in each filter element installation cavity. The air filter element 2 is a filter paper that is continuously folded in a W shape to enhance the filtering area and effect. During actual operation, when air passes through the air filter element 2 longitudinally, the air filter element 2 filters the dust in the air. On the outer walls of the left and right sides of the frame body 11, there are edge limit projections 13 protruding outward, which are used to limit the positions of the left and right edges of the air conditioner filter during installation. At the center of the outer wall of the back plate of the frame body 11, there is a positioning projection 15 protruding outward, which is used to limit the position of the inner end of the air conditioner filter during installation. On the front side surface of the frame body 11, there is an outer baffle 16, and on the outer baffle 16, there is a front handle 3 protruding forward to facilitate the pulling operation during the installation of the air conditioner filter. Above the front handle 3 on the outer baffle 16, there is an outer positioning hook 4, and the outer positioning hook 4 is used for the front-end limit during the installation of the air conditioner filter.
