A while back someone put a link to an Army web-site that rates water treatment devices, and that web-site rated the "pure" chlorine dioxide treatments highly, but they rated the MSR Miox lower since it creates a "mixed oxidants" solution rather than a pure chlorine dioxide.

I really wish someone would do a independent test of the Miox's effecacy for killing Giardia and Cryptosporidium in comparison to chlorine dioxide, boiling, and the UV "pen" technology.
