LumActiv® and COVID-19

In the midst of the current global COVID-19 crisis, inquiries into the capability of the LumActiv product and its ability to promote cleaner and safer work and home environments have increased significantly. We wanted to create this page to clear up any confusion about what LumActiv can and can’t do. The number one asset in a situation like the one we find ourselves in is clear and reliable information.

Photocatalytic Titanium Dioxide has been researched for its ability to break down pollutants, bacteria, and even viruses for well over 30 years. The reactive hydroxyl radical ion that is formed in the photocatalytic process is very well understood and there is little disagreement in the scientific community that these radicals break down or deactivate bacteria and many viruses. However, though there are a number of peer reviewed papers highlighting the ability of Titanium Dioxide to kill bacteria and viruses, LumActiv is not registered with the US EPA as a pesticide product and therefore can make no antimicrobial claims to the general public. The fact is that there is not yet an appropriate category within EPA regulations for photocatalytic materials that distinguish them from traditional harmful pesticides.

Our goal is to provide you, the consumer, with enough scientifically backed information to make a decision on what is best for your home or workplace. Based on the information that is available to us, we are confident in our recommendation of a comprehensive approach to disinfecting that includes a photocatalytic cleaner like LumActiv, as well as traditional cleaning methods.

Since COVID-19 is still a brand new virus, there has yet to be research on the effectiveness of photocatalytic materials at inactivating this particular strain, however the following resources provide information on the effectiveness against similar viruses.

The following two papers can be found at the website of the National Institute of Health’s National Center for Biotechnical Information:

Comparison of Infectious Agents Susceptibility to Photocatalytic Effects of Nanosized Titanium and Zinc Oxides: A Practical Approach “Methods using photocatalytic properties of nanosized TiO2 and ZnO prove to be highly efficient in inactivation of infectious agents…A reduction of infectious agent transmission in the public space can be achieved thanks to the photocatalytic properties of self-disinfecting and self-cleaning surfaces. Their crucial compounds are oxides of some metals, such as TiO2 and ZnO, which, after they have been powdered to NPs, exhibit strong virucidal, bactericidal, and fungicidal properties.”  J. Bogdan et al, Nanoscale Res Lett. 2015; 10: 309. Published online 2015 Aug 4. doi: 10.1186/s11671-015-1023-z

Photocatalytic Inactivation of Influenza Virus by Titanium Dioxide Thin Film.Titanium dioxide (TiO(2)) under ultraviolet (UV) light produces a strong oxidative effect and may therefore be used as a photocatalytic disinfectant…Even with a low intensity of UV-A (0.01 mW cm(-2)), a viral reduction of approximately 4-log(10) was observed within a short irradiation time.” R. Nakano et al. Photochem Photobiol Sci. 2012 Aug;11(8):1293-8. doi: 10.1039/c2pp05414k. Epub 2012 May 14.
