E. Levetin et al., Effectiveness of germicidal UV radiation for reducing fungal contaminationwithin air-handling units, APPL ENVIR, 67(8), 2001, pp. 3712-3715
Levels of fungi growing on insulation within air-handling units (AHUs) in a
n office building and levels of airborne fungi within AHUs were measured be
fore the use of germicidal UV light and again after 4 months of operation.
The fungal levels following UV operation were significantly lower than the
levels in control AHUs.
