Manufacturing/building method(s) Detail regarding solution production or construction method (instructions, mass production capacity, custom made,etc...)

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.
