Hi, I've heard that Lugol's 5% iodine solution is the standard for water purification on treks. However, it is very expensive to buy in the UK. I'm going on the Everest Base Camp trail next month and to save on my costs, was wondering if it might be cheaper to buy the iodine in Kathmandu?
Could anyone recommend me a specific place in or around Thamel where it might be possible to buy a high grade solution to use on the trek? Any brand names you could suggest, which from personal experience were very good, assuming I can't get Lugol's there?
I will be using it as a back up to my water carbon filter so only need a small amount as a back up.
Thanks
