Product Description

Tirta Cupumanik (TCM) are silver enhanced ceramic ‘pot’ water filters for household drinking water treatment manufactured in Indonesia based on the open source technology promoted by Potters for Peace.

Target SDGs

SDG 6: Clean Water and Sanitation

Market Suggested Retail Price

$50.00

Distributors / Implementing Organizations

Manufacturer in partnership with the Ministry of Research & Technology has established a business unit responsible for marketing and distribution, individual sales.

Manufacturing/Building Method

Locally sourced clay and risk husks are processed, mixed with water, pressed into the filter shape and fired to a ceramic state, flow rate tested to ensure product consistency and coated with silver nitrate solution. It is made of a mixture of clay and rice husk burnt about 600-800º C which in turn produces a ceramic pot through a vitrification process (changing the nature of clay to ceramic). Ceramic properties that can absorb oxygen produce fresh drinking water such as jug water.
