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

ION Technology

More Ions, More Disinfection

Clean Air System’s certified ozone-free ionizers generate tens of thousands of ions per second, safely eliminating airborne and surface pathogens and resulting in fresher, cleaner conditions. The ionizers’ precise integration allows for maximum ion production and delivery throughout your space.

Distributed by Airflow

Our fans’ airflow amplifies not only the number of ions that are generated but also their effective coverage areas. Aside from disinfecting air and surfaces, our fans’ airflow improves occupant comfort, HVAC efficiency, and energy savings, providing real benefits for business owners.

Kill Viruses Where People Breathe

An ion’s lifetime is only about 30 seconds, so it’s essential that ions be delivered to the air your people breathe and the surfaces that they touch. Rather than concealing ionizers within ductwork, Big Ass Fans integrates ionizers into our fans to distribute ions directly to your people.

UV-C Technology

Haiku with UV-C

Verified by Third-Party Testing

Independently tested and proven to achieve a 99.99% microbial reduction, Clean Air System’s UV-C technology dramatically lowers the risk of infection for all airborne pathogens. Our airflow experts apply scientific modeling of airborne infection to show you how our powerful air disinfection will provide cleaner, safer conditions for your business.
