SPOUTS Purifaaya Ceramic Water Filter

Founded by Harvard University undergraduates in 2011, SPOUTS of Water created a ceramic water filter to be used for water purification.

Ceramic pot filters are made of a mixture of clay, water, and rice husk. The mixture is first machine pressed into the correct flower pot mold, and is then fired using a traditional ceramic firing kiln. During firing, the rice husk combusts, leaving behind many 0.6-500 μm holes that physically remove contaminants from the water.

The fired filters are then coated with silver nitrate, which acts as a biocide against the residual bacteria that may flow through. The safe water storage reservoir prevents recontamination of treated water. With over 50 filter factories worldwide, ceramic water filters have been historically proven to be effective in removing 99.9% of microbiological contaminants.

The Purifaaya is our original product, designed for households and containing a capacity of 20 liters. The Purifaaya XL, designed for institutions, contains 65 liters and includes a stand. This model is especially popular with schools, health centers, and corporate clients.

SPOUTS manufactures ceramic water filters using local materials. Under the brand name Purifaaya, these filters are distributed to Ugandans to provide an affordable, effective, and easy to use solution to water access in Uganda.
