AU222　superiority

Conventional systems—such as air purifiers—operate by drawing in air and capturing dust, particles, and viruses through filters. Some devices incorporate UV sources within the unit, yet their effectiveness remains limited, as disinfection can occur only after contaminated air has been taken into the device. In contrast, light‑based spatial disinfection acts directly on viruses while they are still floating in the air, allowing germicidal performance to take effect before inhalation occurs. As a result, the risk of infection is significantly reduced.
