How UV Lights Can Help Against The Spread of Coronavirus

The COVID-19 pandemic is far from over, with cases spiking and hospitalizations increasing in almost every area of the country. From mask-wearing to handwashing to physical distancing, following the public health recommendations is everyone’s first line of defense against coronavirus. However, there are some additional protective measures that may at least potentially help prevent or reduce the spread of COVID-19—including the use of ultraviolet (UV) air purification.

Because they are sensitive to ultraviolet heat and light, research studies have shown that UV lights with wavelengths between 200 and 400 nanometers are extremely effective in killing viruses and bacteria. Ultraviolet light destroys bonds that hold the bacteria and viruses’ DNA together, prompting the National Health Commissions to comment in its latest guidelines on the diagnosis and treatment of COVID-19 that “the radiation from UV light can effectively eliminate the coronavirus.”

Fortunately, UV lights do not pose a hazard to human health. Although ultraviolet light does contain radiation, it is safe because it cannot penetrate the eyes or the outer layer of human skin. Viruses and bacteria are much smaller than human cells; therefore, ultraviolet light can reach their DNA and eliminate them without damaging human tissue.
