Cleanrooms are specialized industrial environments where various measures are taken to maintain a highly clean and sterile internal environment to meet specific production or experimental requirements. They are primarily used in industries such as microelectronics, semiconductors, and the production of electronic components.

The working principle of cleanrooms is based on air filtration and negative pressure control, primarily using air purification technology to control the number of airborne particles and reduce microbial contamination such as bacteria and viruses in the air, thereby maintaining cleanliness, eliminating static and bacterial issues.

A cleanroom is a specialized industrial environment, primarily used in industries such as microelectronics, semiconductor, and electronic component manufacturing. During the operation of a cleanroom, strict operational standards must be followed, and regular cleaning and maintenance must be conducted to ensure its high efficiency, safety, and proper functioning, guaranteeing the smooth progress of production and experimental processes.
