UV‑C LED (265‑280 nm) Disinfection Unit for Air Duct (HVAC) Market Trends (2026): Market Leaders Powering Global Indoor Air Quality

MARKET INSIGHTS

The Global UV‑C LED (265‑280 nm) Disinfection Unit for Air Duct (HVAC) market size was valued at USD 1.87 billion in 2025. The market is projected to grow from USD 2.09 billion in 2026 to USD 5.14 billion by 2034, exhibiting a CAGR of 10.6% during the forecast period.

UV‑C LED disinfection units designed for air duct (HVAC) applications are advanced germicidal devices that emit ultraviolet light within the 265‑280 nm wavelength range – widely recognized as the most effective spectrum for inactivating airborne pathogens, including bacteria, viruses, mold spores, and other microbial contaminants. These units are integrated directly into HVAC air duct systems to continuously disinfect circulating air, offering a chemical‑free and highly efficient alternative to conventional air purification methods. Unlike traditional UV‑C mercury lamps, UV‑C LED technology delivers greater energy efficiency, longer operational lifespans, compact form factors, and mercury‑free operation, making them increasingly preferred across commercial, industrial, healthcare, and residential HVAC installations.

The market is witnessing robust expansion driven by heightened global awareness of indoor air quality following the COVID‑19 pandemic, stringent regulatory guidelines around airborne infection control in healthcare and public infrastructure, and rapid advancements in solid‑state UV‑C LED technology that have significantly reduced unit costs. Furthermore, growing adoption in commercial buildings, hospitals, schools, and transportation hubs – combined with increasing investments by key manufacturers in product innovation and strategic partnerships – continues to accelerate market growth. Companies such as Signify (Philips UV‑C), Seoul Viosys, LG Innotek, and Crystal IS are among the prominent players actively expanding their UV‑C LED HVAC product portfolios to meet rising global demand.
