An airlock on board the Space Shuttle. An airlock [a] is a room or compartment which permits passage between environments of differing atmospheric pressure or composition, while minimizing the changing of pressure or composition between the differing environments.
A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well isolated, well controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor manufacturing.
ISO 14644-1 covers the classification of air cleanliness in cleanrooms and associated controlled environments. Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particulates. [6]
Contamination control is the generic term for all activities aiming to control the existence, growth and proliferation of contamination in certain areas. Contamination control may refer to the atmosphere as well as to surfaces, to particulate matter as well as to microbes and to contamination prevention as well as to decontamination.
Air showers are typically placed between a gowning area and cleanroom; after workers don appropriate garb and personal protective equipment, they enter the shower so that the pressurized air nozzles remove any residual particles from coveralls. Once the program cycle is complete, users exit through a second door into the cleanroom.

A cleanroom is an engineered space that maintains a very low concentration of airborne particulates. Cleanroom or clean room may also re also refer to: "The Clean Room", a TV series episode; Cleanroom suit, overall garment worn in a cleanroom; Cleanroom mat, mat with an adhesive surface that is placed at the entrances or exits
Willis Whitfield (December 6, 1919 – November 12, 2012 [1] [2]) was an American physicist and inventor of the modern cleanroom, a room with a low level of pollutants used in manufacturing or scientific research.
