ECOion-copper silver ionization is the most effective technology for controlling Legionella in water systems. In field evaluations, copper silver ionization has yielded the most successful results and is backed by more than 100 independent research studies. Copper silver introduces disinfectant ions that travel throughout the plumbing infrastructure and attack Legionella living downstream, embedded in biofilm within the plumbing distribution system, providing systemic disinfection. Copper silver ionization is essential for controlling preexisting Legionella contamination. This technology provides a controlled release of copper and silver ions into the water supply to kill harmful waterborne pathogens*. Aside from being an effective method for combating Legionella, copper silver ionization is also the most environmentally friendly solution – with no harmful disinfection by-products.
