Abstract: An in-duct air sanitization apparatus features an air sanitizer, and a set of reflectors. A housing of the sanitizer is mountable to a first wall of an HVAC duct, and a UV emitter resides on a working side of the housing that faces into the HVAC duct to irradiate the duct interior with UV light. The reflectors are mountable on interior wall surfaces of the duct to receive and reflect incident light from the sanitizer to ensure thorough irradiation of an entire cross-sectional flow area of the duct interior, thus optimizing the effective UV sterilization of the airflow. The emitter is oriented with one or more bulb axes thereof oriented parallel to the working side of the housing to provide the sanitizer with a compact and conveniently handled low-profile design. The reflectors are mounted magnetically to the duct walls in tool-free fashion with no detriment to duct wall integrity.
