Abstract
A system disinfects air. The system includes an elongated chamber having an inlet configured for air to flow into the chamber. The chamber also has an outlet configured for air to flow out of the chamber, and a sidewall formed from a material that is at least 90% UVC reflective. The chamber defines a longitudinal axis. A LED is positioned to emit UVC radiation in a direction substantially perpendicular to the longitudinal axis of the chamber. A filter is configured to trap pathogens. The filter is formed of a material that is UVC reflective and UVC transmissive.
