How long does the Enviro Swim Systems benefit last?
The length of time over which copper and silver ions remain active against contaminating micro-organisms depends on a number of factors, including water hardness and pH. However, an extensive research program conducted in the USA showed that a hospital water distribution system remained free from contamination for over 3 months after the ionisation system was turned off. This level of residual protection is far in excess of that provided by any other treatment.
