Steri-Spray, a patented ultraviolet (UV) technology that reportedly eliminates the risk of Legionnaires’ disease from commercial showers and taps, has been launched in the UK with the backing of BBC “Dragons’ Den” ‘dragons’, Deborah Meaden and Theo Paphitis.
Invented by plumber and water treatment specialist Ian Helmore (pictured), the Steri-Spray range is now available following rigorous independent testing by public health and safety testing organisation, NSF International, which found that Steri-Spray showers “safely achieve more than double the required germicidal kill rate for Legionella bacteria, without using harmful chemicals”. The range has also been extensively tested by the Belfast NHS Trust and Hertfordshire Fire & Rescue, which both report success in eliminating Legionella from showers. Water flows into the Steri-Spray unit via a flow regulated inlet pipe and safety latching water valve, before entering a UV reaction chamber, where it passes around the outside of a quartz tube encapsulating a UV lamp. UV light passes through and penetrates the water, destroying the bacteria by breaking down their cell wall. Continuous UV lamp operation keeps the shower, shower-head, and non-touch tap, Legionella-free even during low use.
