Commonly Available Filters will only filter out bacteria and other large organisms they will not filter out Viruses. The only Mechanical Filters that will are the Reverse Osmosis Filters. If you check out the sites I posted links to you will find out that they are very expensive and very heavy. The one that actually produces enough water to be useful for Militia use weighs about 7 lbs and costs about $1,800.
