Made in Canada, the Pristine package is made up of 2 parts
Part A 2% stabilized chloride dioxide solution
Part B 5% food grade phosphoric acid solution
Mixing 7 drops of Part A with Part B per litre of water will result in a 5 parts per million solution of activated chlorine dioxide (ClO2). ClO2 has often been has often been used by municipal water treatment plants as an alternative to chlorine in disinfecting and sanitizing water. ClO2 not only effectively kills pesky little creatures, like Giardia and Cryptosporidium, but can also eliminate viruses and bacteria.
Chlorine is currently being phased out due to growing concerns over its carinogenic by-products, principally trihalomethanes (THM's). Other halogens used in water treatment such as flourine, bromine, and iodine are also recognized to have unhealthy by-products. Iodine has been known in particular to affect the thyroid gland. Chlorine dioxide does not produce THM's and does not affect the thyroid gland.
Pristine usually comes with me wherever I travel nowadays. I have used ClO2 many times both here at home in the Canadian Shield and abroad in Asia. Pristine is EPA approved.
