Typical cleanroom head garment A cleanroom or clean room is an environment, typically used in, including of pharmaceutical products or scientific research, as well as aerospace semiconductor engineering applications with a low level of environmental such as dust, airborne, particles, and chemical vapors. More accurately, a cleanroom has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size. To give perspective, the ambient air outside in a typical urban environment contains 35,000,000 particles per cubic meter in the size range 0.5 and larger in diameter, corresponding to an 9 cleanroom, while an ISO 1 cleanroom allows no particles in that size range and only 12 particles per cubic meter of 0.3 μm and smaller.

As employee of the Sandia National Laboratories, Whitfield created the initial plans for the cleanroom in 1960. Prior to Whitfield's invention, earlier cleanrooms often had problems with particles and unpredictable. Whitfield designed his cleanroom with a constant, highly filtered air flow to flush out impurities. Within a few years of its invention in the 1960s, Whitfield's modern cleanroom had generated more than 50 billion USD in sales worldwide.

Overview [ ] Cleanrooms can be very large. Entire manufacturing facilities can be contained within a cleanroom with factory floors covering thousands of square meters. They are used extensively in,, the, and other fields that are very sensitive to environmental contamination. There are also modular cleanrooms.

The air entering a cleanroom from outside is to exclude dust, and the air inside is constantly recirculated through high-efficiency particulate air () and/or ultra-low particulate air () filters to remove internally generated contaminants. Staff enter and leave through (sometimes including an stage), and wear protective clothing such as hoods, face masks, gloves, boots, and coveralls.
