This tutorial show how the ceramic filter works and outlines the main stages of manufacturing. It is aimed mainly at entrepreneurs rather than at individuals. Don’t try to create this technology at home (you need an oven, you need to test materials, etc.). If you are interested in setting up a small factory like this, you will need more training. The Potters for Peace organization in partnership with CAWST and the company Ecofiltro (which we visited in Guatemala) offer this kind of training. All this knowledge is freely available in open-source form.
