Protection Against SARS-CoV-2 (COVID-19 virus) & Other Pathogens

The outbreak and rapid spread of SARS-CoV-2 has had a dramatic impact worldwide as the virus is highly contagious and spreads by air, from contaminated surfaces and via personal contact. Social distancing is a primary strategy being used to slow the progress of SARS-CoV-2 transmission and infection, but this approach is not always viable in healthcare, commercial or industrial settings, where workers and patients are at higher risk and in close proximity to others. For these environments, a solution is needed that can kill airborne viruses and also kill viruses on surfaces, so that the spread of the disease can be slowed and the burden on the healthcare system eased.

HGI Industries sells purification devices that have been proven to kill viruses and bacteria in air and on surfaces. HGI manufactures its air purifiers in Florida, using proprietary UV irradiation technology to safely generate hydroxyls and organic oxidants. Unlike conventional air purifiers, HGI devices do not limit treatment to the air that is pulled through the unit.  The hydroxyls and organic oxidants generated diffuse throughout a room, sanitizing the air and surfaces in the treated space. HGI devices are safe for use in occupied spaces and do not degrade materials such as plastics, rubber, fabrics or electronics.  The levels of hydroxyls and organic oxidants produced are equivalent to the concentrations found outdoors in nature and well within the safe limits established by OSHA.

HGI’s unique attributes differentiate it from other sanitization approaches available in the market:

  • Chemicals used to clean surfaces do not treat airborne pathogens and they emit harmful VOC
  • Standalone germicidal UV can’t be used in occupied spaces, it rapidly degrades materials such as plastics and its efficacy is negatively impacted by shadowing
  • In-duct germicidal UV only treats the air coming into contact with the UV lamps, and the faster the air flow, the more limited the pathogen killing effect, and it does not treat surfaces
  • Ozone generators cannot be used in occupied spaces and they degrade materials and electronics

HGI’s airborne hydroxyls are ideal sanitizing agents.  They react with a broader range of chemicals and are a million times more reactive than ozone, bleach and other agents.  They react so fast that they are consumed within a few milliseconds and never accumulate. Atmospheric hydroxyls are continuously produced by the action of the sun’s ultraviolet energy on oxygen and water in our atmosphere.  They keep air safe to breathe by decomposing natural and man-made pollutants and killing pathogens. They sanitize air and surfaces by a natural process called lysing, where the hydroxyls react chemically with the lipids and protein carbohydrates in the cell wall and membranes of viruses, bacteria and other organisms.  The interior contents of the cells leak and the pathogen is destroyed.  The mechanism for killing the pathogens is not biological, so the viruses and bacteria do not develop any form of immunity.

HGI has conducted several studies in independent labs to demonstrate the safety and efficacy of its technology in destroying pathogens, both in aerosolized form and on surfaces.  These included surface decontamination (porous and non-porous) studies on bacteria, viruses and mold at ATS Labs, where a 4 log reduction (99.99%) of Influenza Type A was achieved in 3 hours on both glass and cotton.

HGI leveraged its safety and efficacy data to obtain FDA approval for its Odorox® MDU/Rx™ device (FDA 510k #133800). The MDU/Rx™ unit is approved as a Class II medical device for use in occupied spaces.

At the Aerosol Research & Engineering Laboratories (ARE Labs), a U.S. laboratory specializing in the study of aerosolized microorganisms, HGI conducted an evaluation of the kill rate on a number of pathogens, including MS2 bacteriophage (ATCC 15597-B1), a positive-sense, single-stranded RNA virus.  The FDA routinely uses MS2 as a simulant for pathogenic RNA viruses such as coronavirus.  The HGI device tested (MDU/Rx™ device) demonstrated a kill rate of 99.999% (5 log reduction) within two hours, and achieved the FDA minimum efficacy level of 99% destruction in only 15 to 20 minutes (see graph below).

HGI sells several portable devices that can treat office and open spaces such as hangers, from a few hundred to several thousand square feet. The size of the treated space dictates the size of the unit. These units are “plug and play” - they are plugged into the wall and turned on - no calibration needed, no training, no cleaning or maintenance.  Only the UV optics need to be changed after 12 months.

Eliminate 99.9% of Viruses, Bacteria, Mold, VOC's, Odors

ODOROX® technology is a proven, 100% green process based on the natural sanitizing power of the sun that scrubs the air and surfaces clean of biological and chemical contaminants. ODOROX® Hydroxyl Generators provide immediate and permanent solutions to combat poor indoor air quality due to bacteria, viruses, mold, volatile organic compounds (VOC’s) and offensive odors.  There are no fumes or harsh chemicals and it can be used safely around humans, animals and plants.

The ODOROX® UV Hydroxyl generating technology uses only ultraviolet (UV) energy to generate a continuous stream of hydroxyls (OH) from water like the sun does outdoors.  Hydroxyls rapidly decompose volatile organic chemicals (VOC) creating a cascade of natural, organic oxidants that kill bacteria, virus and mold safely, restoring Nature’s balance indoors.  The technology is safe as proven by FDA approval of the MDU/Rx™ portable device for use in occupied spaces.

HGI has designed a range of ODOROX® systems to work optimally in a wide variety of industries and applications.  Products include portable, wall and ceiling mounted units as well as air curtains and devices designed to integrate with HVAC systems.  The MVP™ series includes sophisticated interactive process control and sensors to treat up to millions of cubic feet of commercial and industrial space and can be monitored and controlled remotely.  The technology is proven safe when used as directed:  the right sized systems for a given treatment space and proper ventilation.


ODOROX® equipment can solve any indoor air problem.

Our hydroxyl generators mimic Mother Nature’s naturally occurring process for cleaning and purifying our atmosphere.
