This recent, four-page research study from Steril-Aire, Inc. (Cerritos, CA), "Effectiveness of UV Irradiation for Reducing Fungal Contamination within Air-Handling Units," found that the company's "UVC" lights reduced mold contamination up to 99% in test air handlers in an office building. The results include enhanced IAQ, energy savings, and reduced coil cleanings. The study was led by Dr. Estelle Levetin, University of Tulsa.
