Far-UVC: Weighing Disinfection Benefits & Ozone Caution
3 days ago · While far-UVC light effectively sanitizes the air, it also produces ozone (O₃) as a byproduct, which can be a respiratory irritant. The study observed that after one hour of far-UVC operation, ozone levels rose by 4-6 parts per billion (ppb) in the room, with concentrations exceeding 25 ppb near the light source.
