Report on results of University of Surrey air and surface testing

Our study ‘The Future of Cleaning,’ has shown that by using two new technologies, you can significantly reduce the live CFU (Colony Forming Unit) counts on surfaces and in the air to a degree that would certainly reduce the risk of cross-infection in an indoor environment.

The two technologies used were:

Advanced Photocatalytic Oxidation (APO) is an air purification technology that actively reduces airborne microbial activity by filtering air and releasing a safe concentration of hydroxyl radicals. Unlike earlier methods that required high, unsafe levels of free radicals, APO uses a patented process involving titanium dioxide and UVc light to maintain antimicrobial effectiveness below maximum exposure limits, allowing safe use without PPE or room evacuation. 

Photocatalytic Solution (PS) is a surface treatment using similar free radical technology. It is applied every 3 to 6 months and remains effective until worn away through use. While both technologies require continued routine cleaning, PS is being tested for a method to verify its ongoing antimicrobial presence, and APO may also reduce surface microbes, though this effect is not yet published.

To learn more about this, read the attached report on air and surface testing.
