cleanroom standards

While most users still refer to cleanroom classifications in terms of the old federal "209 E" standards, the new generally accepted classification limits are the ISO 14644-1 classes, as follows:

Former Class 100, 000=New ISO Class 8
Former Class 10, 000=New ISO Class 7
Former Class 1, 000=New ISO Class 6
Former Class 100=New ISO Class 5
Former Class 10=New ISO Class 4
Former Class 1=New ISO Class 3

Other "clean" spaces can be Laminar Flow benches, Clean Benches, or Biological Safety Cabinets. They can have vertical or horizontal airflow, and can be designed to protect products, personnel, or both.

The heart of any cleanroom or laminar flow bench is the HEPA filter. The term HEPA stands for High Efficiency Particulate Air. HEPA filters are usually made of boron silicate microfibers cast into thin sheets, much like a sheet of paper. The filter media is folded to increase its surface area.
