Applying Big Ass Fans to Improve Performance of Upper-Room UVGI Systems

The Big Ass Fans team have produced a study showing that installing HVLS fans in tandem with wall mounted UV lights can help reduce the accumulation of airborne bacteria and viruses in large spaces. This study of healthcare facilities by the National Institute for Occupational Safety and Health shows that UVGI effectiveness increases from 12% to 89% when an overhead fan is used to destratify the air in the space.
