How it Works

Harnessing the power of the sun

The OHAir® unit contains a uniquely designed HGU (Hydroxyl Generation Unit) that operates at specific wavelengths to reproduce the effect of the sun’s ultra-violet light, but inside your house.

This is a bit technical, but this how OHAir® technology works:

  1. A pulse of low-wavelength light from the HGU (Hydroxyl Generation Unit) interacts with a water molecule in the air (H2O) removing a hydrogen atom resulting in the creation of a hydroxyl molecule consisting of an oxygen and hydrogen atom (OH).
  2. The newly generated hydroxyl is in a dynamic state as it seeks to recover the hydrogen atom from any molecule it interacts with to convert back to a water molecule.
  3. The Constant Stream effect of the OHAir® unit continues the ongoing generation of hydroxyls, spreading them within the air and onto surfaces in the room.
  4. The dynamic nature of the hydroxyl molecule results in the destruction of any bacteria and virus it contacts by penetrating their cell walls and removes any volatile organic chemicals such as chlorine and ammonia by changing their chemical composition.

The Constant Stream effect

Hydroxyls naturally last less than a second as they interact with other molecules. The unique feature of the Odorox® Technology is the continual generation of Hydroxyls through a Constant Stream effect within the room, while not requiring all air to flow through the unit.

Tried-and-tested

Researchers at Leeds University discovered hydroxyls while dong research into rain in the 1970s. During the 1980s and 90s, NASA developed the first hydroxyl generator that was used on six NASA missions and in the International Space Station.

In the early 2000s, NASA issued licences to some American companies to produce the generators commercially. OHAir’s® parent company HGI began developing units for commercial applications based on the Odorox Technology and in 2012 started work on the domestic version. The units we sell today are the result of many years of tests, trials and application of the Odorox Technology in the USA and Canada. Learn more including testimonials from customers.

Laboratory tests

Extensive testing conducted at ATS labs in the USA confirms the ability of OHAir® technology to destroy harmful organisms in the air and on surfaces in your home. As you can see from this table, many of the bacteria were reduced by over 90% within just a few hours:

FDA Approval

HGI Industries Announces FDA Approval of the Odorox®MDU/Rx Device for Use in Medical Facilities

The Odorox® MDU/Rx™ medical model is an ultraviolet (UV) air purifying device intended for the reduction of bacteria and selected virus in air in medical facilities. Performance data published in the FDA 510(k) summary showed 4 to 5 log reductions in airborne bacteria and selected virus within 1 to 2 hours; a reduction that is equivalent to killing 99.999% of the microorganisms.
