The most science based Legionella control method. 

Over 25 peer reviewed scientific papers support the Orca copper and silver ionisation system. 

There are more papers published in support of copper and silver ionisation than any other Legionella control method. 

The Orca system is also backed by Dr Birgitta Bedford, who extensively confirmed the efficacy of copper and silver ionisation in her PHD on Legionella control (the boxes below contain Dr Birgitta Bedford's research).
