We have already mentioned in several of our previous articles that as we worked with LEDs, different light spectra and wavelengths, we were completely absorbed by this new field of research. Not long after this, the Covid-19 pandemic started and many of our colleagues and partners began working from home. Our company was hit quite hard by the economic downturn because several large orders were canceled or postponed by our partners for understandable reasons. In retrospect, we don’t regret this as our team of innovative engineers was able to focus their creative energy on developing a tool that can benefit everyone.
Ozone generators and their dangers
Light gives life, but it can also take it when it is in the UV range. This is why ozone generators are effective at disinfection. Their problem is that they are not only fatal to bacteria and viruses, but they are also harmful to humans. Therefore, it is not recommended to stay indoors when an ozone generator is running and the room must be ventilated after using it.
Unique light spectrum and nano coating
Our colleagues started researching light spectra that are still in the visible range while still having a disinfectant effect, without producing ozone, which is dangerous to living organisms. When we identified this range, we had to face the fact that unfortunately light alone will not be effective enough. We needed something else. Further research was launched on how to make our device more efficient so that we can disinfect the air in enclosed, indoor areas without using ozone. A joint research began and help came in the form of a polymer-based nanocomposite disinfectant coating, which even has the additional positive property that the surface is self-cleaning and neutralizes unpleasant odors. We coated the surface of the air disinfectant’s lamellae and illuminated them with LED light. Thanks to the combined effects of the light and nano coating, the device showed good enough test results to continue the development of the product. We entrusted testing the device’s efficiency to the professionals, the Department of Microbiology of SZTE. These tests are still ongoing. We expect concrete results by the end of September.
Research in progress
We are aware that measuring the efficiency of an air disinfectant is not a simple process, and opening a door or a window can bring in more bacteria, fungi, or even viruses into the enclosure, thus changing the purity of the indoor air. Our equipment is designed to operate continuously in an enclosed space so that staff can work in complete safety. Another advantage is that it can be used in a car when connected to the cigarette lighter socket due to its low energy consumption. It certainly does not replace but complements ozone generator cleanings so that the air in enclosed spaces remains clean even after ventilation. We realize that our new product is only the first step in the process of achieving breakthrough success in this research field and allowing large office buildings to use their air conditioning and air exchange systems safely thanks to our improved products. However, if we can help slow down the spread of the epidemic and thus protect the health of our own and other companies' employees, it was worth losing a few orders in March-April, as we began developing this product without sparing any expense to help ourselves and others alike.
