Title Airborne fungal contamination in air-conditioning systems: Effect of filtering and humidifying devices
Bibliographic information Nov. 1996, Vol.57, No.11, p.996-1001. Illus. 34 ref.
Abstract Air samples collected above and below filters and humidifiers in air-conditioning systems were analyzed for total culturable airborne fungi and for 4 specific moulds. Two types of filters were studied in four air-conditioning systems. Concentration levels below the high-efficiency filters were significantly lower than those above the filters; filter efficiency was dependent on the fungi. Concentration levels below the humidifier were lower than above it. The association of a high-efficiency filter with a humidifying device containing uncontaminated water reduces the risk of microbiological air contamination. The effect of particle size on filter efficiency is discussed.
