That Berkey water filter looks pretty interesting. I could not find on the website how many microns it filtered down to, but it was definitely at least 0.3 microns, probably 0.2 microns if they also tested for the smallest bacterium. The actual number would be interested as it could then tell you if it removed free viruses as well.

Does anyone know if there is a carbon filter core to it as well? I would imagine the carbon filter component would "wear" out faster than the Berkey filter itself, but they claim 100% removal of VOC's as well, which I would think comes from some sort of filter element.
