[0022] Embodiment 2: A household air purifier filter that is easy to disassemble and assemble, such as Figure 1 - Figure 3 As shown, the clamping mechanism 9 includes an adjusting plate 10, which is a strip plate. Both ends of the adjusting plate 10 are movably connected to the filter frame 7. Two groups of first telescopic springs 11 are arranged at the lower end of the adjusting plate 10. The two groups of first telescopic springs 11 are symmetrically installed on both sides of the lower end of the adjusting plate 10. One end of the first telescopic spring 11 is fixedly connected to the adjusting plate 10, and one end of the first telescopic spring 11 is fixedly connected to the filter frame 7.
