Wouldn't UV light burn your lung tissue as much as kill the virus. You don't have a thick layer of skin for nothing...
Far UVC light could help in stores

“Unfortunately, conventional germicidal UV light is also a human health hazard and can lead to skin cancer and cataracts, which prevents its use in public spaces,”
...
In this study, aerosolized H1N1 virus—a common strain of flu virus—was released into a test chamber and exposed to very low doses of 222-nm far-UVC light. A control group of aerosolized virus was not exposed to the UVC light. The far-UVC light efficiently inactivated the flu viruses, with about the same efficiency as conventional germicidal UV light.
At a price of less than $1000 per lamp—a cost that would surely decrease if the lamps were mass produced—far-UVC lights are relatively inexpensive. This could allow the tool to be utilized in far more places than UV lights are currently being employed, leading to potentially wide sweeping impacts toward diminishing the spread of many infectious diseases.
I wouldn't stick it down my throat though:
“Far-UVC light has a very limited range and cannot penetrate through the outer dead-cell layer of human skin or the tear layer in the eye, so it’s not a human health hazard,” Dr. Brenner noted. “But because viruses and bacteria are much smaller than human cells, far-UVC light can reach their DNA and kill them.”

Maybe but we poision people to cure cancer so... eh, I'm not advocating it, I just thought it was interesting when the media ripped him for it but it turned out to be a legitimate treatment for the lungs a half centruy ago. It certainly blew my mind a little.

Perhaps when you need to be put on an ecmo machine you might as well try this
Ultraviolet Irradiation of Blood: “The Cure That Time Forgot”?
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6122858/
That was replaced by antibiotics, yet those don't work against a virus, add a UVC light to an Ecmo machine and clean the blood while oxygenating it. I don't know if that would be effective or safe (might just kill your anti bodies as fast as the virus)
Here's a study on the effect of UVC on the lungs from a year ago.
https://www.jhltonline.org/article/S1053-2498(19)30118-4/abstract
This is the first clinical trial evaluating a therapeutic intervention during EVLP. As in our pre-clinical studies, UVC does not alter virus quantities measured by PCR (virus fragments) during EVLP, however it does appear to confer impairment in virus infectivity. The combination of UVC therapy with an ultra-short course of direct anti-virus agents may provide the ability to prevent transmission altogether, allowing expansion of transplantation using HCV+ organs.
This is for 'cleaning' the lungs for a lung transplant though. Taking the lungs out of the body, treating them, and putting them back in seems a bit of a hassle :)
