One way schools and universities can mitigate the COVID-19 risk is to utilize their HVAC systems to circulate clean fresh air. In this episode, Mike Wolf, Director of Regulatory Affairs at Greenheck, and Ron Wendorski, Director of the Bernard A. Greenheck Education Center, talk about indoor air quality in classrooms. They explain how foundational technologies like increased air ventilation and filtration can help reduce the spread of COVID-19. They also explain how additive technologies like ultraviolet technology and bipolar ionization can help. We also discuss cost-effective ways to improve HVAC systems and the long-term benefits of indoor air quality.
