The Doulton SS gravity filter is made from high grade polished stainless steel, and is a portable, robust model which is easy to keep hygienically clean.  The SS is very popular with disaster relief organizations, campers, and for everyday home use.  It requires no electricity, and does not need to be connected to home plumbing.  It is a complete and self contained water filtration system.

The SS model comes standard with the following:

The Doulton SS 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 2 ceramic filters.

The Doulton SS 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.  If kept topped up, this system can filter approximately 12 to 15 Gallons (95-115 liters) per day using 7" slimline filters.

Doulton Ceramic Filters have been manufacturered 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.

Each 7" Doulton slimline filter will last up to 535 gallons (1070 for a set of two) before requiring replacement.

Each 7" Doulton Imperial filter will last up to 1000 gallons (2000 for a set of two) before requiring replacement.

A set of 2 fluoride filters will last for approximately 800 gallons.

Due to their effectiveness at eliminating water-born diseases such as cholera, typhoid, E. Coli, etc., these water filters are being specified for field operations by many of the world's major aid and emergency relief organizations.

For customers who do not have a reliable pressurized mains water supply, whether it is at home, on a campsite, or in a holiday cottage, a gravity filter enables you to have clean filtered drinking water on tap. Water is poured manually into the upper chamber. It passes through the filter candles under pressure of gravity into the lower chamber where the filtered water can be accessed via a tap on the front of the filter.

Made from high grade polished stainless steel, the SS Gravity Filter is a portable, robust model, which is easy to keep hygienically clean. The SS is very popular with aid organisations and private customers alike.
