Scientist Johann Wilhelm Ritter first discovered ultraviolet light in 1801. He determined that it was invisible electromagnetic radiation at wavelengths between 10-400 nm. In addition to UVA and UVB, which come to us from the sun, a third type, UVC, has the potential to disinfect spaces. Here are the most frequently asked questions.

As the Earth’s population grows and approaches a projected 9.7 billion by 2050, the world’s freshwaters will face mounting pressure to supply the needs of population growth. Approximately 33 per cent of people do not have access to safe drinking water and a similar number do not have access to proper sanitation — numbers that will increase as populations grow.

From trains, planes and buses to escalator handrails and elevator buttons, the air we breathe and surfaces we touch are now being cleaned at the speed of light. With science showing we're more at risk for coronavirus exposure indoors, industries are scrambling to figure out how to make customers feel safe enough to return. Ultraviolet light devices are seeing increased demand for disinfection.

Water purification remains a prevalent issue in the world today. In many third world countries, drinking water is easily polluted and can lead to the mass infestation of various pathogenic microorganisms in vital water sources. The consequences of polluted drinking water could be catastrophic and lead to global viral pandemics.

According to 2019 FoodNet Report published by the U.S. Center for Disease Control (CDC), incidence of foodborne illnesses continues to increase. Infections from five common food borne pathogens such as Campylobacter, Cyclospora, shiga toxin-producing E. coli (STEC), Vibrio, and Yersinia are on the rise although infectious caused by Listeria, Salmonella and Shigella remain flat.

Pittsburgh International Airport has put UVC fixtures on its floor-cleaning robots, making it the first airport in the US to test the use of the ultraviolet rays to scrub the coronavirus from surfaces. If effective, the UV-cleaning robots could be a model for other airports as they plan to reopen and try to persuade people to travel again.
