Abstract
An air treatment system includes an enclosure, a first UV lamp, a second UV lamp, and one or more air driving components. The enclosure includes an inlet, an outlet, and a passageway between the inlet and the outlet. The one or more air driving components are configured to draw air into the enclosure via the inlet, and to direct air toward the outlet via the passageway. The first UV lamp is configured to output first UV light having a first peak wavelength, and the second UV lamp is configured to output second UV light having a second peak wavelength that is different from the first peak wavelength. The first and second UV lamps are disposed in the enclosure, and each of the first light and the second light irradiates the passageway. A method of operating the air treatment system is also disclosed.
