If DIYing, choose your UV wavelength wisely. UVC (around 254nm wavelength) is germicidal and doesn't produce ozone (it actually dissociates ozone). "Vacuum UV" (in the range 185nm) converts oxygen in the air to ozone, which is highly toxic.

  The point of the parents' posts is that you have these issues with ozone even if you just irradiated the air ducts without direct contact to UVC.

  Hopefully the UV light is blocked from escaping the device.
