3 micron and larger in dimension. The entire air shipped to a cleanroom passes by HEPA filters, and sometimes exactly where stringent cleanliness efficiency is critical, Ultra Small Particulate Air (ULPA) filters are utilised.

Cleanrooms do not entirely take out contamination; in its place, they control it to some tolerable stage. In instances the place functions are more likely to result in defects in the ultimate solution, an increased degree of cleanliness is necessary in order to avoid contamination.
