Cleaning Air with Light Proven Uniquely Versatile
A novel invention using light to remove air pollution has proven to be more versatile than any competing systems. It eliminates fumes as chemically diverse as odorous sulfur compounds and health hazardous hydrocarbons while consuming a minimum of energy.

The name of the air cleaner is GPAO and its inventor, Professor of environmental chemistry Matthew Johnson, University of Copenhagen, Denmark, published the results of testing the system in the article “Gas Phase Advanced Oxidation for effective, efficient In Situ Control of Pollution” in the scientific periodical “Environmental Science and Technology”.
Pollution is notoriously difficult to remove from air. Previous systems trying to control air pollution consume large amounts of energy, for example because they burn or freeze the pollution. Other systems require frequent maintenance because the charcoal filters they use need replacement. GPAO needs no filters, little energy and less maintenance, explains atmosphere chemist Matthew Johnson.
“As a chemist, I have studied the natural ability of the atmosphere to clean itself. Nature cleans air in a process involving ozone, sunlight and rain. Except for the rain, GPAO does the very same thing, but speeded up by a factor of a hundred thousand”, explains Johnson.
In the GPAO system, the polluted gas is mixed with ozone in the presence of fluorescent lamps. This causes free radicals to form that attack pollution, forming sticky products that clump together. The products form fine particles which grow into a type of airborn dust. And whereas gas phase pollution was hard to remove, dust is easy. Just give it an electrostatically charged surface to stick to, and it goes no further.
“Anyone who has ever tried dusting a computer screen knows how well dust sticks to a charged surface. This effect means that we don’t need traditional filters, giving our system an advantage in working with large dilute airstreams”, says Johnson.
Removes foul smells as well as noxious fumes
Patented in 2009, the system has been commercialized since 2013 and is already in use at an industrial site processing waste water. Here it eliminates foul smells from the process and saved the plant from being closed. A second industrial installation removes 96% of the smell generated by a factory making food for livestock. Further testing by University of Copenhagen atmospheric chemists have shown that the GPAO system efficiently removes toxic fumes from fiberglass production and from an iron foundry, which emitted benzene, toluene, ethyl benzene and xylene.
Another series of tests revealed that the rotten egg smells of pig farming and wastewater treatment are easily removed. Odors such as the smells from breweries, bakeries, food production, slaughterhouses and other process industries can be eliminated. And that is not all, says Professor Johnson.
“Because the system eats dust, even hazardous particles such as pollen, spores and viruses are removed” states Johnson, who hopes to see his system in use in all manner of industries because air pollution is such a huge health risk.
According to a recent report by the World Health Organization, indoor and outdoor air pollution causes 7 million premature deaths annually which is more than the combined effects of road deaths, smoking and diabetes. Pollution in air is linked to heart disease, cancer, asthma, allergy, lost productivity and irritation.
“I have always wanted to use chemistry to make the world a better place. I genuinely feel that GPAO will improve life for millions of people, especially those living in cities or near industrial producers” concludes Matthew Johnson.
