Cheong, C.D., Neumeister-Kemp, H.G., Dingle, P.W. and Hardy, G.E.St.J. (2001) The use of HEPA air filters to control airborne indoor fungi. In: IAQ 2001; Moisture, Microbes and Health Effects: Indoor Air Quality and Moisture in Buildings, 4 - 7 November, San Francisco.
The influence of portable HEPA filtration units on the composition and levels of airborne fungi in the bedrooms of asthmatic children was investigated over a 15-week study period. Reductions in airborne indoor fungal levels (70%) and particulate matter (38%) were achieved in homes fitted with the portable HEPA filtration units. Although the total numbers of indoor fungi were reduced after the installation of the HEPA filtration units, the variety of fungal genera remained relatively unchanged, reflecting a similar species range as that of outdoor air. In combination, the use of portable HEPA air filtration units, regular maintenance of both filter material and carpets, and a general awareness of indoor air issues, such as ventilation and source control, could aid in reducing exposure to airborne indoor fungi in residential environments.
