To begin to tackle the subject of water purification, one must first understand the difference between purification and filtration.

• Water Filtration: The removal of bacteria, protozoa, and general sediment from water.
• Water Purification: The removal, or act of rendering waterborne viruses inactive as well as the removal of bacteria and protozoa.

Purification would seem to be the obvious choice of the two, but without a specific tool for that purpose one may be forced to use other methods. Optimally, one would use a filter and a chemical to sanitize the water.

Possible chemical treatments;

• Iodine ie. Potable Aqua
• Chlorine Dioxide ie. Katadyn Micropur

Popular filter choices:

MSR Miniworks EX Water Filter

Katadyn Hiker

Katadyn Pocket Microfilter
