Ultraviolet (UV) light has been gaining traction as a potential solution to the spread of COVID-19, but is it really effective? While UV light can be an effective tool in eliminating viruses and bacteria from the air, it is not recommended to use it within a HEPA filtration system. UV light works by altering the chemical bonds in DNA, which prevents bacteria from replicating and transcribing. The International Ultraviolet Association states that most UV lamps used for disinfection contain mercury. To be effective, a UV air purifier must be equipped with the right technology and produce UV light at a specific wavelength and intensity.
The Center for Disease Control (CDC) and the Environmental Protection Agency (EPA) do not recommend using UV light in HEPA air purifiers. This is because UV lights can be costly, difficult to maintain, and can even damage HEPA filters. Despite the widespread belief that UV light can eliminate COVID-19 from the air, the CDC does not recommend using it within a HEPA filtration system. Home air purifiers with UV light have become popular during the Covid-19 pandemic as they help prevent the spread of hospital-acquired infections. Although UV rays provide an extra layer of protection, it is important to validate the device with the manufacturer to ensure that it produces a high enough dose of UV light to inactivate any virus or bacteria.
Low-quality UV lamps do not produce the required dose, so it is essential to check with the manufacturer. In conclusion, while UV light can be effective in eliminating viruses and bacteria from the air, it is not recommended to use it within a HEPA filtration system. It is important to validate the device with the manufacturer to ensure that it produces a high enough dose of UV light to inactivate any virus or bacteria.
