Pure for Giardia
Polar Pure water purification comes in a glass bottle.
In the bottom are iodine crystals that continuously
saturate the water in the bottle.
For normal water you put two capfuls of iodine solution
per liter of water. You can easily make two or three
liters of water at a time.
Then you fill the Polar Pure up with water again,
and the iodine crystals in the bottom saturate the
new water with iodine.
Over time, the iodine crystals eventually are used
up. But one bottle of Polar Pure will make about 2,000
liters of water.
A small plastic trap in the Aqua Pure bottle prevents
the crystals from fall out when you pour the iodine
solution into the cap.
Warning - Neither Polar Pure nor any other iodone
based water purification will touch cryptosporidium.
That, plus the taste, is why we more highly recommend
is even a small thermometer on the side of the bottle
to tell you have many capfuls of iodine to put in.
The reason for this is that the warmer the water temperature,
the more concentrated the iodine solution in the Polar
Pur Bottle. The cooler the water, the less the concentration.
It's basic chemistry.
My experience with the little thermometer on the sides
of Polar Pure bottles is that it quits working after
awhile. Then you're back go guessing the concentration.
But the product is still quite usable.
