The working situation of HEPA filters needs to be checked to start with. In adequately functioning HEPA filters, the quantity of airborne microbial contamination is very small. In unidirectional air flow zone, microbiological sampling is done from the 4 corners from the perimeter zone, one particular from the center and 4 from the inner corners of the interior zone.
