[0002] A cleanroom filter is a device used in a cleanroom environment to effectively remove airborne pollutants such as particulate matter, microorganisms, and harmful gases to maintain the indoor air at a specific cleanliness level. It is typically composed of filter material, a frame, and sealing components. The filter material can be fiber, filter paper, activated carbon, etc., which can capture and adsorb tiny particles and harmful substances in the air. The frame provides structural support to ensure the stability and integrity of the filter. The sealing component is used to prevent unfiltered air from bypassing the filter and entering the cleanroom. However, the cleanroom filters currently on the market still have the following problems:

[0003] Existing clean room filters are usually fixed with multiple threaded connection structures. During the maintenance process, disassembly tools are needed to disassemble them one by one before the clean room filter can be removed for maintenance, which makes the disassembly steps before maintenance more cumbersome. At the same time, when disassembling the clean room filter, the clean room filter can only be disassembled as a whole, and cannot be adjusted and disassembled according to the specific situation of the clean room filter, which means that the flexibility of clean room filter disassembly still needs to be improved.

[0004] In response to the above problems, an innovative design was carried out based on the original clean room filter. Utility Model Content
