As far as I know Purifloh is not using any devices to sterilise rooms/surfaces as yet @Pixie - they are trying to purify the air and I imagine via aircon systems but I suppose they could be stand alone systems too. But I have a feeling most people here are wondering why there has been no 1 month trial results. The second trial would not be finished, 3 to 4 months at at dedicated TB ward at a medical college, after initial set up delays but I would have thought we should have heard something by now from the first trial at the Gov chest hospital.
