Our friends over at American Apocalypse posted about a drip water kit available from an on-line dealer, I was able to find out that you can order this from the manufacturer directly.
"It is described as, "A ceramic, half-micron water filter. The micron removes water-borne bacterium. The inside of the filter is loaded with different media or ingredients, such as man-made carbons, mother nature carbons and man-made resins. Those different resins and carbons remove the different contaminants in the water."
