Harnessing the power of natural systems

Odorox® – Hydroxyl Generator Systems

The Odorox® brand means odor oxidation, and the name fits since Odorox® devices use oxidation technology to eliminate odours and solves any indoor air and surface contamination challenge.

With the Odorox® device product line:

• Numerous toxic gases and their associated pungent odours are neutralised.
• Bacterial, viral, and fungal species are under constant control.

  • Destroy Staphylococcus aureus bacteria in the air and off surfaces and materials
  • Destroy Escherichia coli (E-coli) bacteria in the air and off surfaces and materials
  • Destroy Listeria monocytogenes bacteria in the air and off surfaces and materials
  • Destroy Influenza A virus in the air and off surfaces and materials

• Mold spores and colonies are neutralised.
• Odorox® device users notice that pests are not able to locate food particles and pests leave.
• Towels stay free of mildew and musty odours.
• Odorox® device users tend to have longer sleep cycles.
• Odorox® device users see a reduction in the need for puffers and inhalers.

A patented process has been developed through years of testing. This process mimics the way Mother Nature cleans and purifies the atmosphere. Odorox® technology safely restores the balance of indoor air to nature’s fresh, safe state.

Odorox® technology harnesses the same UV energy as found from the sun and humidity to create atmospheric hydroxyls to provide a mechanism to sanitise the air and surfaces. Odorox® devices do not use any chemicals. Odorox® hydroxyl generators are certified by Electrical Testing Labs (ETL) for safety and quality assurance through the world’s largest independent testing, inspection, and certification partner – Intertek. The U.S. Environmental Protection Agency (EPA) recognises that atmospheric hydroxyls are a naturally occurring molecule and are safe.

Odorox® generators come in different sizes and are scalable to meet the needs of most situations. The generators are used for disaster restoration, mold mitigation, sewage backup, neutralising Volatile Organic Compounds (VOCs), biohazard, trauma clean-up, residential air odours, surfaces, or purify the air.

What are atmospheric hydroxyls?

Atmospheric hydroxyls (HO· or ·OH) are naturally occurring free radicals and in the literature are often called “Nature’s Broom.” They are essential common radicals in the outside atmosphere. Mother Nature uses these radicals to rid the outside air of odour, mold, and bacteria. Mold doesn’t grow in direct sunlight due to several factors including atmospheric hydroxyls. They really “Restore the Balance” and are “Green Technology at Work.”

Hydroxyls are created in our atmosphere when the sun’s ultraviolet energy reacts with oxygen, ozone, or water vapor in any of the following ways:

• Activated oxygen species strip a hydrogen atom from H2O generating HO·.
• UV absorption of H2O also causes the loss of a hydrogen atom, generating HO·.
• Ozone (O3) decomposes to form HO·.

Atmospheric hydroxyls produced by the sun’s ultraviolet light are the most important cleansing agents in our environment:

• According to the National Aeronautics and Space Administration (NASA), the sun produces steady concentrations of atmospheric hydroxyls at 500,000 to 2.6 million molecules / cm3
• Atmospheric Hydroxyls keep the air fresh and decomposes organic and inorganic compounds
• Destroys ozone, methane, volatile organic compounds (VOCs), and peroxides
• Kills pathogens in air, porous materials, and surfaces

Atmospheric hydroxyls are environmentally friendly and safe

The average person breathes an average of 13,250 litres of air each day. This means that with every outdoor breath you are inhaling 1.5 billion hydroxyls! Fresh, outdoor air can be up to 100 times cleaner than the air indoors. That is because hydroxyls clean the air outside. No other cleaning agent is more natural, pure, and harmless. Once hydroxyls latch on to an allergen, bacteria, or odour, it is neutralised without any risk to people, pets, or plants. Skin, mucosa, and plant surfaces are impermeable to atmospheric hydroxyls.

Atmospheric hydroxyls—an unmatched disinfectant

Hydroxyls are the second fastest oxidising agent in nature and:

• React with >5,000 organic compounds, more than any other oxidant
• Destroy ozone, methane, CHCIF’s, VOCs, peroxides
• Keep air “fresh” - decompose organic & inorganic volatile compounds
• Kill pathogens in air, porous materials, and on surfaces 
• Creates a cascade of other free radical oxidants that also help cleanse
• Are 2 1⁄2 times more effective than chlorine and 13 times more effective at oxidizing pollutants than ozone (O3)
• Are over one million times faster at oxidising than O3*, peroxides, etc.; (only fluorine – which does not occur naturally, is faster)
• Neutralises at the molecular level and can penetrate and purify any porous object including: wood, rubber, plastic, vinyl, textiles, electronics and other sensitive materials
• Decompose in < 1 second and do not accumulate
• Create free radical chain reactions faster than positive and negative ionic reactions


About Odorox product technology

Although the Odorox equipment varies in size and use, the science and technology behind each generator is the same. The generators create efficient ultraviolet (UV) energy using proprietary quartz optics and an optimised reflector designed to maximize the generator’s deodorising and disinfecting capability.

As shown in Figure A., contaminated air is directed through a reaction chamber where ambient humidity and multiple UV nanometer wavelengths and frequencies combine to create an oxidising formula that purifies the air/surfaces and produces atmospheric hydroxyls.

• The first segment of the chamber deodorises the airflow with the oxidising UV source.
• The second segment destroys bacteria as well as other micro-organisms and prevents them from multiplying.
• Throughout the process, wavelengths combine with ambient air and humidity to create hydroxyls, which are the key to the decontamination process. The result is a dual process attack on contaminates:
• The processing chamber sanitises airflow and produces atmospheric hydroxyls
• The hydroxyl free radicals exit the chamber to decontaminate surfaces and contents
