The Functioning situation of HEPA filters needs to be checked initially. In properly functioning HEPA filters, the level of airborne microbial contamination may be very very low. In unidirectional air movement zone, microbiological sampling is completed with the four corners in the perimeter zone, a single from the center and four through the internal corners with the interior zone. This zone shouldn't contain more than 0.5 CFU/m3.

In the heat sterilization method, the for a longer time the publicity to heat, the better the sterilization in a provided temperature. Because the temperature of warmth rises, some time span essential for sterilization decreases.
