I beleive he's referring to the Katadyne Mp-1 tablets, which are chlorine dioxide, not iodine.


I'm not suggesting that boiling is always the best option, though it may be if you have abundant fuel and a large enough pot. However if you're going to boil anyway, then there is no reason to use chemicals.

I agree with what Izzy had said about carrying a 32 oz bottle, this is why I harp on the Guyot Designs stainless steel backpacker model bottle, it's 32 oz which is 1 dose with a steripen or 1 tablet with a Katadyne micropur tablet (backup for the steripen). It makes it easy for treating and in a pinch you can boil water in it as well plus no plastic taste or leaching. Best thing since fried chicken for me.

Add a one liter Platypus bag to your kit.


But I would do a double dose in an emergency.

Love the Platypus bags... Rolls up small...

I have pondered getting the fold flat water bags from bepreparedtosurvive. They look nice too.

I carry the 2L Platapus in my backpack.

Have both... love the flat water bags for kits. don't have to worry about the cap getting in the way when folded.
