Abstract

Embodiments of the present technology are directed to air treatment reactor modules, and associated systems and devices. An exemplary reactor module can include a housing, an ultraviolet (UV) light source disposed within the housing, and a plurality of hollow elongate conduits disposed within the housing and peripheral to the UV light source.
