Cleanrooms are enclosed environments that initially were created for use wherever high standards for air quality were required, for instance, physics research laboratories. In the 1960s, improvements in air filtering systems and air flow regulation greatly expanded the usability of cleanrooms and they were quickly adopted by industrial and medical establishments, such as pharmaceutical manufacturing, semiconductor manufacturing, and negative-pressure rooms in hospitals. International Standards Organization ranks cleanrooms from 1 to 9 according to the density and size of airborne particulate matter per cubic metre. ISO Class 1 is the cleanest room with a density of 12 particles per cubic metre and the size of the particle no larger than 0.3 microns. To put the size in perspective, the tip of a human hair is between 60 to 100 microns.

Cleanrooms function by filtering the air coming into the cleanroom and continually filtering the interior air through a HEPA and/or a ULPA filter. Air flow is generated through a unidirectional laminar system or a multidirectional turbulent system. The aim of air movement is to drive particles towards the filters. Contamination is stringently controlled by using non-shedding materials, such as stainless steel, in the construction of the walls and equipment, restricting material being brought into the cleanroom, and having personnel wear cleanroom suits and enter through an air lock entrance.

The cleanroom manufacturer now services an increasingly diverse range of industries that require contaminant-free air. Once the modern cleanroom was established, different applications sprang up to keep the cleanroom manufacturer and cleanroom supplier racing to balance supply and demand. Often the applications of cleanrooms are the result of changing expectations in other industries. Just as an example, two areas that are putting pressure on the cleanroom manufacturer and cleanroom supplier are the increased control over food processing standards imposed by international trade regulations, and a higher accountability surrounding the gathering and processing of forensic evidence required by legal systems. provides a network through which the cleanroom manufacturer and supplier can locate reliable business partners and keep up-to-date on novel applications of cleanroom technology.
