Hi Kaiwinthrop,
Welcome, and thanks for your contributions! Do you work with pot filters yourself?
Re pot filters, there is also a Ceramic water filters article - might have been a bit hard to find. Do you want to move your contributions to there? Or is there a difference in these technologies?
Inspired by your contributions, I added a section on the dung-fired filters developed for E Timorese villages, at Ceramic water filters#Dung fired clay pot filters. Hope to see you around here. --Chriswaterguy 01:07, 9 September 2011 (PDT)
