I love the fact that water treatment technology continues to evolve and bring new ideas to the marketplace, however this device concerns me for one very large reason. Aside from protozoa and bacteria in water, there are also a multitude of other things that are floating around in water, things that chemical means (neither chemical tablets, iodine, or the MIOX) are capable of destroying.
I live in Michigan, and here we have what is known as the Hydated Tapeworm, it is primarily carried by Moose and Wolves, and is rampant in Isle Royale National Park. The problem with the worm is that is has a fairly thick protein shell around its eggs (as do some other parasites) that can survive everything but boiling. It is for reasons like this that I seriously question this device, I have used it for drinking water out of lake superior but would not consider drinking from an inland lake (moose feeding grounds)
If you don't have the tapeworm in your area this filter may work great, but definitely look into it before you buy one.
