Mission: Aid and support to ceramic artisans in developing countries
Target demographics: in an advisory capacity
Direct beneficiaries per year: put thousands of filters into homes in the developing world. We also helped hundreds of potters in Nicaragua.
Geographic areas served: Nicaragua and globally
Programs: Ceramic Water Filters: We maintain a database of open-source documents and provide technical advice for any organization or enterprise that wants to start a filter production factory in the developing world.
Nicaragua Program: We provide technical and material assistance to indigenous potters to help improve their standard of living by improving their artistic level of excellence and by helping them improve energy efficiency in their kilns.
I've donated to this organization several times (though not as much as I'd like, being only a grad student). I learned about them from another research group testing their drinking water filter pots. I especially like that they train others to set up self-sustaining filter facilities, instead of simply giving out pots without guidance. I've heard from many sources that working with communities this way is the best way to help!
I've also purchased a product off their website and donated to have a card sent to a friend, and both items were handled well.
Finally, I greatly respect the leadership for taking very little salary and putting most funds toward good works (according to their tax forms). While I don't choose charities based on this, it does show how invested they are in their work.
