Top 10 Companies in the UV‑C LED 265nm Germicidal Air & Water Purification Module Market (2026): Market Leaders Powering Global Hygiene

MARKET INSIGHTS

Global UV‑C LED 265nm Germicidal Air Water Purification Module market size was valued at USD 0.84 billion in 2025. The market is projected to grow from USD 0.97 billion in 2026 to USD 3.12 billion by 2034, exhibiting a CAGR of 15.6% during the forecast period.

UV‑C LED 265nm germicidal air and water purification modules are compact, solid‑state devices that emit ultraviolet light at a wavelength of approximately 265 nanometers – a range recognized for its exceptional ability to inactivate a broad spectrum of microorganisms, including bacteria, viruses, and mold spores. Unlike traditional mercury‑based UV lamps, these modules employ deep UV light‑emitting diode (LED) technology to deliver chemical‑free, mercury‑free disinfection across air handling systems, drinking water treatment units, point‑of‑use purification devices, and surface sterilization applications.

The market is gaining strong momentum spurred by heightened global awareness of waterborne and airborne pathogen risks, increasingly stringent water quality regulations, and accelerating demand for energy‑efficient disinfection solutions across residential, commercial, and industrial segments. The post‑pandemic emphasis on indoor air quality and safe drinking water continues to underpin adoption of UV‑C LED modules. Key players operating in this space include Nichia Corporation, Seoul Viosys, SETi (Sensor Electronic Technology), LG Innotek, and Crystal IS (an Asahi Kasei company), each advancing proprietary deep‑UV LED chip designs and module integration capabilities.
