Household Water Treatment and Safe Storage Fact Sheet: Ceramic Candle Filter CAWST (2009)
Locally produced ceramics have been used to filter water for hundreds of years. Ceramic candles are hollow cylindrical forms fastened into the bottom of a container. Water seeps through the ceramic candle
and falls into a lower container, which is fitted with a tap at the bottom. Units often use more than one candle because the flow rate through one candle can be slow. A lid is placed on top of the filter to prevent
contamination. This system both treats the water and provides safe storage until it is used.
