What is a cleanroom?

A cleanroom is a controlled environment that is designed to maintain extremely low levels of airborne particles, contaminants, and pollutants. It is a specially constructed space where the concentration of airborne particles, such as dust, microbes, aerosol particles, and chemical vapors, is meticulously regulated to meet specific cleanliness standards.

Cleanrooms are used in various industries, including semiconductor manufacturing, pharmaceuticals, biotechnology, aerospace, electronics, and medical device manufacturing, where even the tiniest particles can have a significant impact on the quality and performance of products or processes.

To achieve the required cleanliness level, cleanrooms employ advanced air filtration systems, including High Efficiency Particulate Air (HEPA) or Ultra-Low Penetration Air (ULPA) filters, to continuously remove particles from the air. Additionally, strict protocols for gowning, personnel behavior, and material handling are enforced to minimize contamination.

The classification of a cleanroom is based on the maximum allowable particle count per cubic meter of air and is denoted by ISO classes, ranging from ISO 1 (the cleanest) to ISO 9 (the least clean). The higher the ISO class number, the more particles are permitted in the environment. Cleanrooms play a vital role in ensuring product integrity, safety, and compliance with industry regulations.
