Is there a problem with building a higher clean room class than needed?

Every time you go up a clean room class or down a class in a clean room it has varying levels of cost, space and design requirements. For instance if you go up one class clean room classification from a iso class 8 clean room which is a class 100,000 clean room to a iso class 7 clean room which is a class 10,000 clean room, that change is going to take twice as much air.

Clean room class and air handling

The cost of filtering and circulating that air is the largest cost associated to a clean room environment and the clean room classification for the environment. That translates to the amount of filters, HEPA filtration, air handlers, air returns, air conditioners and all of the space that these components will require. So a simple difference from an iso class 8 clean room class to an iso class 7 clean room is actually significant when you add up all of the variable elements. This could account for a 25% difference in cost for the same size clean room at a cleaner classification I.e. iso 8 Cleanroom and iso 7 cleanroom.

Key takeaway: Classification for Cleanrooms should be carefully chosen to fulfill the needs of the cleanliness classification, the cost and budget of the cleanroom and the spacial and design requirements. Changes to the classification will have a significant affect to the cost of the cleanroom and many requirements and design parameters will have to be considered when trying to achieve a higher level of cleanliness or cleanroom classification.
