Indoor air quality has become an increasingly important consideration across residential and commercial environments as organizations invest in technologies that support healthier indoor conditions. The U.S. Environmental Protection Agency states that indoor pollutant levels can sometimes be two to five times higher than outdoor levels, while the global indoor air purification market was valued at approximately USD 24.7 billion in 2024. These shifts have encouraged engineers and environmental researchers to revisit how air systems interact with buildings, electricity, and airborne particles.
Professor Gal J. Nahum has spent more than a decade exploring Conducted Direct Current, or CDC, as part of that broader discussion. His work examines how electrical configurations may influence particulate interaction within controlled environments and how those concepts could eventually connect with existing air management systems. Rather than positioning CDC as a finished commercial solution, Nahum explains it as an evolving framework that is still under active exploration.
