Commercial Biosand Filter

So, saw a link for this company that produces slow sand water filters. Looks very very interesting and of course the science is very sound. One thing I noticed is they don't seem to have prices posted if you wish to purchase one. If your not a do it yourself-er, you might want to look into a few of these for your place. If things go south you can at least know that you can provide your family with a safe source of water. If you can afford several of these, you can have some for barter or set them up for the neighbors to use.

anyways,, these filters are a time proven and science proven technology,, you should look into either purchasing one or building one for your family in case the shit does hit the fan! At least you will know there wont be any shit in your water...
