Proven Technology

Big Ass Fans’ revolutionary Clean Air System is the only solution that incorporates scientifically proven ion and ultraviolet (UV-C) technology to eliminate airborne pathogens and safeguard your space. Both of these technologies are safe, effective air disinfection methods, but which process works best depends on the size, layout, and needs of your space.

Ion Technology

Air disinfection with ionization utilizes positively and negatively charged ions to attack and inactivate airborne contaminants. Integrated at the precise point of airflow, Big Ass fans’ ozone-free ionizers safely introduce tens of thousands of ions per second into your occupied space. Driven by our fans’ powerful airflow, these ions bond to and neutralize contaminants before they can circulate throughout your space, providing cleaner, purer air for your people to breathe.

UV-C Technology

Shortwave ultraviolet (UV-C) technology has decades of proven success eliminating pathogens, but no solution has ever wielded it as effectively as Clean Air System. With UV-C fixtures seamlessly integrated into their designs, Big Ass fans circulate the full volume of air in your space through the disinfection zone above the fan, destroying viruses, bacteria, and other harmful particles, and providing purified air to your people.
