This still seems kinda scary. The scatter off the walls seems like it would be a problem for eyes or even skin over time. Would it generate ozone? What are the by-products of ionizing dust and what happens when you breath them?

The good thing about far uvc is it isn't penetrating. It doesn't it make it through your your outermost cornea or epidermis layers.
Scatter is also negligible as long as its set up competently: reflectivity is very different for UV and visible light.
Ozone production certainly limits the maximum power that can be used, but as I understand it you don't need to crank anything close to max power to attenuate the airborne viral load.
