Dust Free Duality Mini UV AutoSens Mini-Split UV Air & Surface Purifier

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.

Why Add UV Protection to a Mini-Split System?

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.

• Helps reduce microbial buildup on damp HVAC surfaces
• Helps control musty odors from mini-split air handlers
• Supports cleaner coils and better airflow
• Helps maintain system efficiency over time
• Designed for compact ductless and HVAC installations

What Makes the Duality Mini UV AutoSens Different?

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.
