The Doulton SS4 model holds 2.25 gallons of filtered water. When assembled it stands 19" tall and is 8.5" in diameter. The upper chamber nests within the lower chamber for transport and stands only 13" in height. This system can hold up to 4 ceramic filters.

The Doulton SS4 is easy to use. The water you would like to filter is poured in the top chamber where the ceramic filters are installed. Gravity pushes the water through the filters and clean water is stored in the bottom chamber.

Doulton Ceramic Filters have been manufactured in England since 1827. The outer ceramic Sterasyl shell is made of diatomaceous earth with silver incorporated into the ceramic structure to prevent bacterial grow through and makes the filter self-sterilizing. Underneath the ceramic shell is granular activated carbon to reduce chlorine, organics, VOC's, and remove foul tastes and odors. Ceramic filters can be cleaned when the flow rate starts to slow down by using a scotch brite pad or brush under running water.
