[0002] Air filters are divided into four types: coarse efficiency, medium efficiency, sub-high efficiency and high efficiency. Different numbers of air filters are installed in a pipe according to the air volume. The filter section is installed in the central air conditioning system to filter out dust particles in the indoor air to achieve high quality of indoor air.

[0003] The existing graphene filter is composed of a multi-layer filter structure to achieve a good filtering effect. At the same time, users can disassemble and assemble the filter structure according to their needs. However, the combination method of the existing filter structure is a snap-on method, so there are gaps between the multiple filter structures. When filtering and purifying the air, the air can easily flow through the gaps, resulting in this part of the air failing to pass through the filter purification, affecting the filtering effect of the filter.
