So is this that essential kit to be packed for a couple of days walking. Maybe not… but this is a serious piece of kit that deserves respect!
Originally developed for use by the US Military this water purifier works by mixing a very small sample of your suspect water with salt crystals to make a saline solution. Then by passing a strong electric current across it end up creating a very powerful but short lived bleaching agent (MIOX – Mixed Oxide) that when added to your suspect water sample will eliminate most micro-organisms – even that most resilient of water-borne pathogens – Cryptosporidium.
Among its advantages are its light weight and ability to knock out viruses that some water filters are unable to remove. However that said it does have a number of disadvantages – for example it relies upon batteries, testing strips and a supply of salt crystals. And whilst it purifies water against most micro-organisms – it cannot be forgotten that other agents such as chemicals (e.g. agricultural or industrial) and solid matter can still contaminate your water supply even after MIOX treatment.
So whilst I might not pack this for a weekend walk I would seriously consider it for an expedition abroad where I might question the water supply.
A serious piece of kit? Definitely!
