Good news! If you combine this type of UV light with air filtering, then this should be very effective!
Instead of applying this UV light to the room itself, it should perhaps be applied separately to filtered air external to the room and this air is then piped back into the room.
"Far ultraviolet-C light can reduce the level of airborne microbes in a room by more than 92%, according to a new study by researchers in the UK and the US. ...
A decade ago, researchers at Columbia University in the US discovered that a different wavelength of UVC light, known as far-UVC light, would be just as effective at killing germs, but without the safety concerns. This is because, at 222 nm, its wavelength is too short to penetrate human skin or eye cells. "

From the abstract:
"Many infectious diseases, including COVID-19, are transmitted by airborne pathogens. ... One potential solution is Krypton Chloride (KrCl) excimer lamps (often referred to as Far-UVC), which can efficiently inactivate pathogens, such as coronaviruses and influenza, in air. ... While there is laboratory evidence for Far-UVC efficacy, there is limited evidence in full-sized rooms. For the first time, we show that Far-UVC deployed in a room-sized chamber effectively inactivates aerosolised Staphylococcus aureus. ..."
