Quick answers to questions about ordering, compatibility, and installation.
The Dust Free Duality Mini UV AutoSens is a compact, high-performance UV air and surface purifier designed for mini-split systems, ductless air handlers, and tight HVAC spaces.
Built with dual-spectrum ultraviolet technology, dual UV LED arrays, and an integrated VOC filter, this system helps keep damp HVAC surfaces cleaner while supporting better airflow and system performance.
Mini-split indoor units naturally collect moisture during cooling operation. Over time, that moisture can contribute to microbial buildup, musty odors, and reduced efficiency. The Duality Mini UV AutoSens is engineered to help address those problem areas directly inside the air handler using UV-A and UV-C irradiation, VOC filtration, and automatic airflow-based operation.

Unlike bulky HVAC UV lights designed for ductwork, the Dust Free Duality Mini UV AutoSens is made specifically for confined HVAC spaces. Its compact UV LED strips fit inside mini-split air handlers, while the clip-on airflow sensor allows the system to operate only when airflow is detected. Durable 3M adhesives help simplify installation across a variety of system layouts.
