As an FYI, the filter worked great, make sure you use a nice thick cloth as opposed to the little bit of bandanna I did in the cap. Expect the charcoal to color the water, but do not judge it by the color. Some of the worst water can be beautifully clear. The water I purified came out of the city sewer drain in front of my home so I was guaranteed that it was nasty. The down side, it had a slight charcoal taste to it; the upside, I didn’t spend the next three days on the toilette.
The video is me, but it was too large to upload and I’m not clever enough to condense it. So I uploaded it on YouTube and linked it in. Enjoy.
