UV-C (100nm-280nm): The germicidal UV light is effective in microbial control. Scientific research has proven that the most effective frequency for microbial destruction is between 200nm and 280nm, which is within the UV-C band, therefore, as long as the nm wavelength of a germicidal lamp is within that range, the microorganisms will be destroyed effectively.
UV-C light damages the bacteria at a cellular level; it destroys their DNA or RNA structure, so the bacteria can no longer reproduce. It is also effective at eliminating “superbugs”, the type of pathogens that have developed a resistance to modern medicine, and are hard to eliminate with chemical sprays. UV sanitizing wands have been tested and proven to eliminate 100% of several types of bacteria commonly found on surfaces within 5 seconds, and inactivate 90% of hardy spore-forming bacteria in 40 seconds. According to the research, a UV-C device is a reasonable alternative to using chemicals to disinfect surfaces.
