Advanced Production methods often require very clean air and in many cases these requirements are certain to increase. For example the electronics industry needs a very clean manufacturing environment for their VLSI circuit production (VLSI - Very Large Scale Integrated). The pattern width on the circuits can be 1 micrometer or less. The need will be to control particle contamination down 1/10 of third dimension (0.1 micrometer).
The "heart" of the clean room is the filter, but there are a number of considerations regarding room classification, choice of filter, and how filters influence the environment.
