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

Purifaaya is mass produced at the SPOUTS factory in Uganda. The raw materials (black clay, yellow clay, sawdust, and grog) are grinded and mixed together. The mixture is pressed into the filter form and touched up. Filters are fired in a wood-burning kiln at 900 °C. The sawdust is combusted leaving micropores, the main form of physical filtration. Filters are painted with silver nitrate for chemical disinfection. They are then packaged and distributed to various partners.
