The International Standards Organisation (ISO) has a 1 to 9 ranking system for cleanrooms, with 1 being the highest standard of cleanroom. The rating is based on the number of airborne particles per m3 and the particle sizes.

A cutting edge, sensitive pharmaceutical production facility may require an ISO 3 (Class 1) high specification cleanroom to meet the strict industry regulations whereas in medical packaging the cleanroom may only need to be ISO 7 classification (Class 10,000).

Puracore® cleanrooms have been designed and can be customised to each individual order to meet the standard and classification required.
