The upper bucket has a “standard” (normally available on the market) ceramic filter, the filtered water drips into the lower PVC bucket and can be used with a small tap. The lower bucket is well closed for safe storage.

The filter system needs only a minimum of maintenance (regular cleaning of the outside of the ceramic element and inspection and cleaning of the inside of the buckets). The filter candle can be used for six month up to several years, depending on the quality of the water to be filtered.
Two types of ceramic filters candles are recommended:<br>
# A “slow speed” ceramic filter candle, made in India, costs about 1 US$ (in local shops) and can filter 3 litres of water per day. This candle can be impregnated with silver for additional security.
# A “high speed” filter, with additional silver and active carbon already inside, made in Brazil, costs about 3US$ and can produce 25 litres of safe water per day.
The filter bucket is transparent. Users can see how much water is present both in the filter unit and in the lower storage unit. It also is directly visible when the filter candle needs to be cleaned. This improves trust and a better management of the available water in the household.
