Title Microbiological load of a ventilation system filter
Original title Mikrobiologische Belastung des Filters einer Lüftungsanlage [in German]
Bibliographic information Jan.-Feb. 2003, No.1, p.8-9. Illus.
Abstract Some employees of a dairy working in humid environments were found to suffer from repeated respiratory diseases. It was therefore decided to investigate the possible causes. It was found that the filter of one of the three ventilation systems was humid while the other two were dry, and that it contained very high levels of endotoxins and moulds, since their proliferation is favoured by humidity. This problem was related to a faulty design of the ventilation system which used partly re-circulated air mixed with fresh air, a process which allows energy savings. The article emphasizes the importance of controlling the air in production facilities equipped with ventilation systems.
