Effectiveness
Ionization is an effective industrial control and prevention process to eradicate Legionella in potable water distribution systems found in health facilities, hotels, nursing homes and most large buildings. In 2003, ionization became the first such hospital disinfection process to have fulfilled a proposed four-step modality evaluation; by then it had been adopted by over 100 hospitals. Additional studies indicate ionization is superior to thermal eradication.
A 2011 study by Lin, Stout and Yu evaluating 79 research papers found Copper-Silver ionization to be the only Legionella control technology which has been validated through a proposed four-step modality evaluation.
