In 2012, Researchers at Duke University Medical Center used ultraviolet radiation (UV-C) to nearly eliminate drug-resistant bacteria in 50 hospital rooms, reducing the number of bacteria by more than 97%.

2. Reduce colds and flus – germs are not re-circulated by HVAC system
3. Reduce smells / odors
4. Remove VOCs
5. Are more effective in humid climates than dry climates
6. Reduces clogging in condensate drain lines by preventing algae growth.
7. Maintain a cleaner coil, improving cooling efficiency and reducing electricity costs.
