As described in the article, far UV does not appear to be directly dangerous to humans at all. However it does produce Ozone, which can be dangerous - the question is how significant that would be in real, world settings, which is being studied.

Study it all they want, I really don't want to be under artificial UV in an office setting for 8-10 hours a day. Especially since the germs will eventually become immune to it under such persistent steady evolutionary stress. We have enough cancer contributing technologies in our life already without adding more ozone and UV.

Right, but just because it doesn't appear to be dangerous doesn't mean it won't be in the long term. Unless there've been studies already done on the effects of long term exposure, I'm inclined to be cautious. Things like this can have long term effects that aren't immediately apparent.
