HEI has developed a unique capability that significantly reduces the number of toxins in the air and on surfaces, becoming the industry leader for improving the environment in which many people must work, travel and live.

HEI is founded around people who have a unique combination of experience that defines its mission. The team is a collaboration of exemplary specialists in light interaction, wastewater treatment, ozone generation, air duct design, and air precipitation resulting in the development and use of new technology to kill bacteria and viruses that live in moist environments, use FUV light to treat room and duct air, and capture fine particles.

The result is Far UV source (Sterilray™) technology, proving to be 10,000 times more effective in killing bacteria and viruses and destroying toxic substances than mercury lamps or traditional chemical and steam cleaners.
