N. 86 - Indoor air filtration system microbial monitoring

The filtration system of building should be regularly monitored to be sure they are not broken or uncorrectly fixed or contaminated. The HVAC (Heating Ventilation, Air Conditioning) may be responsible for the production and spread of airborne micro-organisms in buildings. The reason of this test is to guarantee the health of rooms, laboratory, hospital and building occupants. The reported “SOP” (Standard Operating Procedure) can help the building servicing engineers in their task. The principle of the test is the comparation of the outdoor microbial population (upstream) with the indoor of the building after filtration (downstream).
