Big Ass Fans

UVGI Technology

UV light has been a scientifically proven technology for over 70 years.
By incorporating UVGI (UV-C) technology with our fans, we are able to move pathogens*
through the upper-room – continuously returning the air where it’s needed most – to the people below.

The Big Ass Fans Clean Air System UVGI (UV-C) Antimicrobial Technology **kills 99.9% of viruses in the air in 20 minutes.
Virus testing includes SARS-CoV-2 and PhiX174 bacteriophage.

Clean Air System

UV-c Technology

  • Big Ass fans circulate air through the upper-room where UV-C fixtures are present.
  • LED indicator lights illuminate to show that the fan is killing pathogens.**
  • Big Ass Fans’ UV-C system produces more dilution airflow than a typical commercial HVAC system.
Air Purification


  • Competitors’ in-duct systems with UV-C must continuously run to clean occupied spaces.
  • In-duct systems use UV-C within the ductwork, not in the rooms where people interact.
  • In-duct UV-C applications are limited by the airflow delivered by the HVAC system.
