The author argues against the effectiveness of in-duct UV systems for air purification, citing several key limitations. A primary concern is the limited applicability, as most homes globally do not have ducted HVAC systems. Furthermore, these systems only function when the HVAC blower is active, which is typically only a fraction of the time, and continuous operation is energy-intensive and potentially detrimental in humid climates. The author suggests that alternative solutions like standalone air purifiers, far-UVC, or upper-room UVC are generally more effective. AI
