click on See How It Works and click on the Step-by-Step View for quick slide show.

The kit is $33 with mixing container, storage container, filter, and chemicals. Chemicals are $20 for enough for 2.5 gallons.

It's more expensive than ceramic filters, but it may be faster if you need potable water quickly. The problem is you need the chemicals every time. With ceramic filters, you can reuse them for some period of time.


I have to say that it's in mine opinion a poor solution for the "third world", like shown in the video. It requires a constant supply of the chemicals, which makes people highly dependent on the supplier. Solutions should be self sustainable for those people, by using local available materials. UV pasteurisation in PET bottles or home made ceramic filters are much more sustainable.
