==Field experiences==

According to the UN in 2009 over a quarter of the population of Senegal still did not have access to clean drinking water. However, even the “clean” drinking water can pose a problem due to contamination of pipes that are left open to aspirate with the municipal water supply is not adequate or from the contamination of wells. Ceramic candle filters are a cheap and cost effective means of combating water born illnesses for families in cities and villages alike. However, candle filters are not used as widely in Senegal as they are in other parts of the developing world, most notably South America. In Senegal the use of the filters suffers from a lack of availability and publicity about their effectiveness. Entrepreneurs are starting to import them from abroad but without a serious promotion campaign, most Senegalese are unaware of their benefits. However, there is no question about the quality of the filters available.

A comparative study between a variety of ceramic candle filters, including the low cost filters imported into Senegal and the top of the line British Birkfield filters, showed very little statistical difference between the performance of the filters. The $4 USD filters imported from Brazil work just as well as the $40 USD filters made in the UK. The study, titled “A Performance Study of Ceramic Candle Filters in Kenya,” can be found on the MIT.edu website.
