Ultraviolet or UV light has been used for decades to disinfect drinking water, hospitals, and surgical rooms. Research shows that UV light kills microorganisms, including the C19 virus.

This technology is gaining traction throughout the cleaning industry in the hunt for ways to disinfect surfaces reducing the spread and exposure to germs. Today, the use of UV light has become a powerful tool to disinfect surfaces and neutralize airborne forms of C19 during cleanings. Today UV light is used to sanitize factories, warehouses, airplanes, subways and buses.

How much of the virus is killed depends on the UVC exposure. It could potentially work in apartment cleaning, especially on high-touch surfaces and in order to reduce the risk of exposure between guest and occupants.

The technology does have its limitations. Effective UV light application must be used when occupants are not around as it can cause burns and eye damage. There’s growing research in something called far UVC—a shorter wavelength of UVC light that is equally as effective in killing viruses, without human health risks.

Boeing has used far UVC to disinfect its washrooms for years and says the technology works inside 3 seconds to kill viruses. The company says the UVC technology will roll out as a cleaning wand, disinfecting in a fraction of the time as chemical disinfectants.

Because the spectrum of UV products is relatively new, it’s unknown what agency—EPA, FDA, FTC–will eventually regulate UV-based products. At the present, UV products found online are unregulated and likely, ineffective.
