I'm off on a 6 month trip around Southeast Asia soon. I'm considering bringing some sort of water treatment system, although I've heard that bottled water is safe and readily available most of the time. Pumps don't seem to be worth the expense, hassle of carrying them around, pumping, moving parts maybe breaking, cleaning, etc. At the very least I'll be bringing a bunch of Katadyn Micropur tablets which I have used before with good results:
Pros: Easy to use, small and light, tastes good
Cons: Expensive, probably can't buy them over there when I run out
Any suggestions for other treatment options? Anyone have experience with the UV treatment options like the SteriPEN?
Is there anything in Southeast Asia that wouldn't be killed by Katadyn tabs / SteriPEN?
