Chaosmagnet,

The Miox is another chemical system, basically a different form of tablet. You make a fresh solution of mixed antioxidants for each run. The salt is converted by electrolysis into a suite of antioxidants, including chlorine dioxide. The big advantage of this is that there is no expiration date. You may also make as much or as little as you need (within the design of the system). It is much larger and heavier if you don't expect to use it much, much lighter and less expensive if you are going to make lots. It is certified to kill everything, but, like tablets, you have to wait. Hours if you have to kill cysts - one of the most common problems in North America, and world wide. An excellent system if you are at a base or using a vehicle and can have multiple containers. Good if you are prefiltering and only need to kill virus (only a 15 min. wait). Not bad if you can wait. Not so good IMO if you are hiking and wish to limit the number of containers you carry.

Respectfully,

Jerry
