What is cleanroom?

A cleanroom is a controlled environment with a low level of pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors. It is designed to minimize the introduction, generation, and retention of contaminants that could adversely affect processes, products, or equipment within the room.

Cleanrooms are essential in industries where even tiny particles or contaminants can have significant impacts on the quality and integrity of products. These industries include pharmaceuticals, biotechnology, electronics, aerospace, and healthcare.

Key features of cleanrooms include specialized ventilation systems, air filtration, controlled temperature and humidity, and stringent protocols for personnel entering and working in the cleanroom. The design and classification of a cleanroom depend on the specific requirements of the industry and the processes conducted within it. Cleanroom classifications are often defined by standards such as ISO 14644-1, which specifies the maximum allowable particle counts in the air within the cleanroom.
