Any type of sodium chloride salt can be used, including granular salt, rock salt, or other. Food grade salt is recommended since it dissolves rapidly and is easy to add to the brine bottle.
Any non-salty water, including the water to be treated, may be used to mix the brine solution. It is recommended to use the cleanest water you can find, but you do not need to bring any special water from home.
No, the device is not a filter. It generates a fresh disinfectant that is added to the water to be treated, much like disinfecting tablets are added to water.
Treated water will contain chlorine residual to help protect it from recontamination and that residual may impart a chlorine taste. This is the same chlorine residual that the US EPA requires in the drinking water coming from the faucet in your house and the ability to taste it provides verification that you have ongoing protection of your treated water. The amount of chlorine left in the treated water will depend upon how much was consumed when treating it.
Potable Aqua PURE generates a more concentrated disinfectant to purify larger volumes of water. Generating a more concentrated disinfectant takes more time, so the device will cycle longer for larger volumes (cycle time can be as low as 20 seconds for 1L and as long as 3 minutes for 10L).
The Potable Aqua PURE Electrolytic Purifier has been tested against and shown to meet the requirements identified in the U.S. EPA Guide Standard and Protocol for Testing Microbiological Purifiers, destroying over 99.9999% of bacteria, 99.99% of viruses, and 99.9% of protozoa when used as directed. Tests have also shown compliance with aspects of the World Health Organization’s (WHO) Household Water Treatment Standard.
The Potable Aqua PURE device can be expected to treat more than 60,000 liters* of water over its lifetime with no replacement parts. Each complete battery charge can generate enough disinfectant to treat about 150 liters* (40 gallons) of wter and the integrated solar panel can transform one hour of sunlight into treatment of 2 liters* (1/2 gallon) of water.
*Volumes are based on one standard dose in alignment with the EPA Guide Standard for Microbiological Water Purifiers. Treating for Cryptosporidium requires more than one dose.
