A "cleanroom" is a controlled environment area (CEA) typically used for manufacturing items that require a low level of environmental pollutants.
Airborne particles are also controlled within a cleanroom!
Sharpie products, such as the Ultra Fine Tip Retractable Permanent Marker, are produced in a cleanroom, making their products cleanroom certified!
