UV-C Lights and Indoor Air Quality Improvement

This white paper discusses the role of UV-C lights in enhancing indoor air quality (IAQ), particularly in the context of the COVID-19 pandemic, which highlighted the importance of clean indoor air. It outlines how UV-C technology serves as an effective method for disinfecting air by destroying airborne pathogens, thereby improving health outcomes for building occupants. The paper details the detrimental effects of poor IAQ, which can lead to various health issues, including respiratory diseases and increased susceptibility to infections. It also presents the Clean Air in Buildings Challenge initiated by the federal government, aimed at encouraging building owners to adopt strategies for better ventilation and air filtration. Furthermore, the paper explains the mechanisms of UV-C light in inactivating microorganisms and discusses the integration of UV-C systems with existing HVAC systems to enhance their efficiency. The document concludes by emphasizing the need for layered approaches in improving IAQ, combining ventilation, filtration, and UV-C disinfection.
