UVGI Systems’ original product, the ‘Nightingale’ unit, was deployed in a long-term (two year) test in four high dependency rooms, used for the treatment / recuperation of immune compromised patients at Basingstoke North Hampshire Hospital, UK.
Two of the high dependency rooms contained UVGI ‘Nightingale’ units, offering a dedicated pressurised and sanitised room environment at a significantly lower cost to that of a central plant system. The third room used positive air pressure sanitisation and the fourth room contained a placebo unit.
In controlled laboratory tests, colonies of microorganisms growing in air samples taken from the rooms using the UVGI ‘Nightingale’ technology showed a significant reduction in measured mean colony count, when compared to those taken from the positive air pressure and placebo environments.

Tests using the ‘Nightingale’ pre-production unit took place at the UK Government Health Protection Agency (HPA) test house, Porton Down. The performance evaluation of the UVGI purification unit tested air samples in triplicate at four flow rates (600, 930, 1260, 1600 m3/h) against microbial aerosols of:
