Illumipure, a Houston-based manufacturer of LED lighting and disinfection systems for commercial and institutional applications, has developed an enclosed air disinfection chamber that eliminates >99% of airborne pathogens, including viruses, mold, and bacteria. The patented Air Guardian disinfection chamber uses the Violeds UV LED technology from Seoul Viosys and Sensor Electronic Technologies, Inc. (SETI), global providers of UV LED technology and subsidiaries of Seoul Semiconductor. 

Designed to be placed inside a return duct, plenum, or mounted in a ceiling, the patented Air Guardian system features Illumipure’s patented Immaculight four-stage protection process:

  1. Surface-mounted fans draw indoor air through the titanium oxide (TiO2) ceramic filter inlet
  2. Air travels through a chamber coated with proprietary material excited with UV-A LED light 
  3. Air travels through a chamber >18 linear feet / >19 square feet surface area irradiated with UV-C LED lightL
  4. Exhaust air travels through a carbon filter to eliminate fine particulates

The Air Guardian disinfection system with Violeds technology is designed to protect human health without emitting ozone, using harmful chemicals, or releasing toxic materials, and employs both UV-A and UV-C light sources, as well as a multi-layer filtration system to disinfect and remove particulates, pathogens, and pollutants. Specifically, the Air Guardian systems’ fan and disinfection chamber sterilize airborne pathogens, including SARS-CoV-2 (COVID-19), MRSA, salmonella, E. Coli, mold, spores, and bacteria with an effective sterilization rate of >99%.

Available in either 2-foot by 2-foot or 2-foot by 4-foot aluminum enclosures designed for ceiling or duct mounting, the patent-pending Air Guardian system is suitable for use in health facilities, labs, and clinics. Moreover, the system is U.S. FDA-certified under Medical Device Classification Class 1, Listing #D420497, EPA Establishment #98105-TX-1, and FDA Facility #10077990. It also carries certification by CE, ETL, and RoHS.

“The Air Guardian disinfection system represents a breakthrough for combatting airborne pathogens in a safe and effective manner,” says John Higgins, Illumipure’s president and CEO. “Using proven technologies that combine UV-A and UV-C light sources with advanced multi-layer heterogeneous filtration, our system is demonstrated to sterilize more than 99% of airborne pathogens on a continuous basis.”

“When we were developing the Air Guardian system, our research led us to the Seoul Viosys/SETi Violeds UV LED technology, which was demonstrated to sterilize 99.9% of the coronavirus in just 30 seconds,” adds Higgins. “The Violeds modules deliver the superior performance, uncompromising quality, and unparalleled reliability that we required to make the Air Guardian system the world class standard in UV disinfection technology.”
