Iodine is so yesterday! and tastes frankly eeeeuuu even after applying so 'screening ' like vitamin C (although that part is good for you!)
Heads up:
KATADYN Micropur Forte Sodium Hypochloride + Silver chloride
Disinfects and protects water for up to 6 months-
As used on many expeditions (and by myself in Africa) in conjunction with
Katadyn's Pocket Filter-
IMHO, the best combination you can get for reliable, cleaned, high volumes of water (0.2 micron ceramic depth filter -cleanable) and no batteries required.
Let's face it- Katadyn give a TWENTY YEAR guarantee on this filter- says a great deal -
Tip:
when buying the Micropure Forte Check the expiry date- many shops stock it for a long time and if often it is within a few months of its use by date.
The liquid is way cheaper than the tablets by a very long mile- Not as practical but using a diabetic syringe, you can measure up the right dose and they are tiny! 1ml per 10 litres of water
