A ceramic pot filter consists of a flowerpot-shaped pot, made from a porous ceramic material. Water poured into a ceramic pot filter percolates through the pot material, and is collected in a second container.

Ceramic pot filters usually have a diameter of about 30 cm by 25 cm deep, with an 8 litre capacity. Two variations of ceramic filters, flat-bottom and round-bottom, are currently manufactured. The ceramic pot typically sits or hangs in the top of a larger plastic or ceramic container (20-30 litres), which is fitted with a tap at the bottom. A lid is placed on top of the filter to prevent contamination.

Local production of the filters is common and preferable. A quality control process to ensure filter effectiveness is required. The lower container, lid and tap can usually be purchased locally.
