Pure Home Water Ceramic Pot Filter (MIT Manual)¶

Ceramic Filtration • Est. CapEx: $20 USD • Lifespan: 3 Years (Replace Element)

Technical Overview¶

A detailed open‑source manufacturing manual for ceramic pot filters (CPFs) developed by MIT and Pure Home Water for Ghana. Provides step‑by‑step instructions for local production using clay, rice husks, and colloidal silver, aimed at NGO factories and community enterprises.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Ceramic Filtration
Capital Cost (CapEx)	$20 USD
Power / Energy	100% Gravity / Zero Power
Target Scale	School / Clinic / Cluster (50–200 people)
Standard Lifespan	3 Years (Replace Element)
Technology Maturity	Commercially Available
Primary Mechanism	Clay mixed with rice husks is pressed into a flower‑pot shape and fired at ~850°C, burning out the husks to create micropores. The fired pot is coated with colloidal silver, which deactivates bacteria by binding to their DNA. Gravity drives water through the porous ceramic into a clean receptacle.
