Unlike water treatment by filtration or ultraviolet light, disinfection with mixed oxidants generated be the PA PURE® Electrolytic Water Purifier leaves a trace amount of chlorine in the treated water. The presence of this little bit of residual chlorine disinfectant after the appropriate wait time confirms treated water is suitable to drink and provides extended protection against potential recontamination.
In most cases, only one standard disinfectant dose from the PA PURE Electrolytic Water Purifier is needed to achieve the necessary levels of microbial inactivation*, leaving that small amount of residual chlorine behind. However, if Cryptosporidium is suspected, or your water appears cloudy/dirty and Giardia is a concern, then more than one dose may be required.
*When used as directed, the PA PURE® Water Purifier achieves required inactivation levels for specific micro-organisms as described in NSF/ANSI/P231, EPA Guide Standard & Protocol for Testing Microbiological Water Purifiers.
