Description and Operation
The British Berkefeld gravity water filters consist of two polished stainless steel containers. The Clean water drips from the filter candles into the lower containerupper container has 4 holes in the bottom, is slightly narrower than the lower container and has a ridge just above its base. For transportation and storage, the open end of the upper container slides inside the lower container, protecting the candles and saving space. In use, the upper container is turned around and, supported by the ridge, sits securely on the top of the lower container. The 4 holes are for the filter elements called 'candles'. The holes are for the candles. The more candles, the more water can be filtered in any particular period. Unused holes are sealed with rubber grommets. The lower container has a single hole near the bottom for the tap and a rubber ring to stand the filter on. A lid covers the top of the upper container to stop dirt, insects and animals contaminating the water.
