 clean room
 clean room[′klēn ‚rüm]  (engineering) A room in which elaborate precautions are employed to reduce dust particles and other contaminants in the air, as required for assembly of delicate equipment.clean roomAn assembly room for precision products whose quality would be affected by dust, lint, or airborne pathogens; usually has smooth room surfaces to prevent dust collection; air precipitators or filters keep dust, lint, etc., to a specified minimum level.clean roomA room in which the air is highly filtered in order to keep out impurities. Chip fabrication plants use clean rooms where the air is completely exchanged as much as seven times per minute. Workers go through an elaborate procedure to gown themselves in the "bunny suits" that are required to keep them from contaminating the atmosphere. Clean rooms are also used in the manufacture of hard disks, and they keep the environment free of infectious bacteria and viruses in the biotech industry. See also clean room technique.

 clean roomA highly filtered environment used to manufacture and/or package sterile and high purity products—e.g., microprocessors, pharmaceuticals, and other dust or microbe-sensitive products—to protect personnel, equipment, and products from microbial contamination and to prevent the escape of hazardous substances into the environment
 clean roomA controlled environment facility in which all incoming air passes through a filter capable of removing 99.97% of all particles 0.3μ m and larger. The temperature, pressure, and humidity in the room are controlled. Clean rooms are used in research and in controlling infections, esp. for persons who may not have normally functioning immune systems (e.g., individuals who have been treated with immunosuppressive drugs in preparation for organ transplantation).In very rare instances a child is born without the ability to develop an immune system. Such children are kept in a clean room while waiting for specific therapy such as bone marrow transplantation.See also: room clean room
