Potters for Peace Ceramic Water Purifier¶

Ceramic Filtration • Est. CapEx: Low-cost / Locally fabricated

Technical Overview¶

An open‑source, low‑tech ceramic water filter program that has established over 50 factories in 30+ countries. The filter achieves ~99.88% pathogen removal by combining porous ceramic filtration with colloidal silver, and is sold at $15–$25 per unit.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Ceramic Filtration
Capital Cost	Low-cost / Locally fabricated
Primary Mechanism	Terra‑cotta clay mixed with sawdust or rice husks is pressed into a bucket‑shaped vessel and fired at ~860°C, burning out the combustible to create pores. The filter is then coated with colloidal silver, which kills trapped bacteria. Gravity pulls water through the ceramic into a plastic receptacle with a spigot.
Target Scale	Household / Village Cluster
Standard Lifespan	10 - 20 Years
