Ultraviolet (UV) light is a powerful germicidal agent that can be used to disinfect surfaces and air. It is a form of electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays. As these lights work, they slowly lose their effectiveness as a germicidal agent by approximately 15 percent each year. After three years, the system will not be able to generate enough UV-C light to neutralize the growth of bacteria and mold.
In addition, running a UV lamp for more than three years not only wastes energy, but the ballast and bulb can also overheat and eventually fail. All three forms of UV light occur naturally, but they differ in wavelength. UV-A radiation has the longest wavelength and can therefore easily enter the Earth's atmosphere. UV-B radiation has the second longest wavelength and is most commonly known to cause sunburn.
UV-C radiation has the shortest wavelength and is only available on Earth from inorganic sources. The lifespan of a UV lamp depends on the product and the design. The LED lamps in the Clearwin railing sanitizer and CLEARSCAN UV-C stylus are guaranteed to last 10,000 hours. Ultraviolet light reassures you because harmful bacteria die before they can affect you or your family.
Unlike traditional UV disinfection systems, which operate 24 hours a day, the new automated systems emit UV light depending on the use of heating, ventilation and air conditioning. Many hospitals have AtmoSair BPI and UV lamps to be proactive against bacteria and COCs (Contaminants of Concern). Therefore, it is important to design UV-C disinfection systems so that they emit the right amount of UV light to prevent the spread of pathogens without causing harm to people or surfaces. UV lights do not treat any of the air in the occupied space, nor are they effective against VOCs (Volatile Organic Compounds) and odors.
Unlike sunlight, UV-C lighting systems are artificially manufactured, allowing engineers to mitigate risks and ensure safe use. UV light has a long history of use as a disinfectant, but it's still common for people to have questions about UV products. No matter what type of bacteria you're trying to avoid, an UV light may be a good option for you. UV light is an effective, practical and environmentally friendly method for disinfecting surfaces to prevent the spread of pathogens.
For more information on UV lamps and other clean air solutions for your home, contact Scott's Heating & Air Conditioning. For most UV disinfection systems, following an annual replacement program will ensure that UV lights continue to keep the indoor air in the home healthy. UV lamps are especially useful for those who might be considered “at risk” when it comes to COVID-19. Adding UV light to the air conditioning system can reduce the risk of your family suffering from diseases and allergic reactions, as well as soften odors associated with coil growth.
