British Berkefeld Gravity System with Doulton Ceramic Filters



This system is manufactured in the UK of 304 grade, polished Stainless Steel. It is hygenic, durable, corrosion resistant and easy to clean.

This system comes complete with 2 x Doulton Supersterasyl Ceramic Filters.

Doulton filters can be used to filter alternative water supplies and are used by military, aid and relief organisations and missionaries around the world.

Perfect for camping, caravaning & travel. Set up is approx. 50 cms high and 22 cms wide. Packs into a box 40cmx30cmx30cm.

This cutaway graphic shows the two chambers, each of which holds 8 litres (excluding the capacity consumed by the filters).

This system is designed to filter the top chamber of unfiltered water, storing the filtered water in the bottom chamber.

Please note this system does not have a seal between the two chambers, therefore can be overfilled if adding more water to the top chamber than what is dispensed from the bottom chamber. 




Doulton Supersterasyl Ceramic Filters  

  • Highly Effective Barrier To Particles and Pathogens - a pore structure down to 0.2 microns to offer maximum protection. 99.99% plus filtration of bacteria, cysts and particles. Suitable for use on all alternative and town water supplies.
  • Long Life / Long Term Value - Test results guarantee removal for 2,000 Litres and the ceramic surface of the filters can be easily cleaned.
  • Natural - The ceramic is made from 100% natural earths and uses coconut shell activated carbon.
  • Minerals Maintained - the filters do not remove those minerals from the water which are beneficial to health.
  • Enhanced Anti-bacterial Properties - Silver impregnated ceramic walls makes these filters superior to other ceramic filters and prevents microbiological growth.
  • Humanitarian Aid - This filter is used by military, aid/relief organizations, and missionaries around the world.
  • No Power Required / No Water Wastage - Cost effective to run and environmentally friendly. Healthy water that doesn't cost the earth!


Over a million filters sell each year in over 150 countries around the globe, where Doulton is a household name synonymous with clean, healthy drinking water.

Consider the rest then go with the best!

How it works: Simply add water to the top chamber, which sits on top of the main storage container. Under the force of gravity the water first passes through the micro porous ceramic walls of the filter. The inside of the walls of the Doulton filter are impregnated with silver. The silver acts as a natural biocide to keep the water inside your filter, and also your stored water, pure. Then the water passes through the activated carbon filled core of the filter. From there it drips into the storage container at the bottom.

WHAT IS Super Sterasyl®?

The Sterasyl® ceramic is filled with granular activated carbon to produce the Super Sterasyl™ filter element. Among other things, activated carbon is very effective at removing chlorine and organics from water.

Super Sterasyl® uses granular activated carbon instead of an activated carbon block in order to give superior flow rates in a gravity filter.

Supersterasyl membrane: (candle and cartridge form): Used for microbiological removal. The only ceramic element in the world to meet the stringent NSF antimony and arsenic extraction test featuring:

  • >99.99% E.coli removal
  • Tested with live Cryptosporidium cyst to 100% removal far exceeding EPA three log cyst reduction requirements
  • 100% efficiency at 0.9 µm absolute (0.5 µm absolute ANSI standard)
  • > 98% efficiency at 0.2 µm
  • > 90% efficiency at 0.05 µm

 How Activated Carbon Works to Filter Your Water

Activated carbon or AC, works by attracting and holding certain chemicals as water passes through it. AC is a highly porous material, therefore it has an extremely high surface area for contaminant adsorption.( Adsorption is the phenomenon whereby molecules adhere to a surface with which they come in contact with. When water containing soluble organic materials comes into contact with the granular activated carbon it selectively removes these materials by adsorption.)  
AC is made of tiny clusters of carbon atoms stacked upon one another. The carbon source is a variety of materials such as peanut and coconut shells or coal. the raw carbon source is slowly heated in the absence of air to produce a high carbon material. The carbon is activated by passing oxidizing gases through the material at extremely high temperatures. The activation process produces the pores that result in such a high adsorptive rate.

Laboratory Test results show these filters are very efficient at removing impurities such as chlorine, bacteria, amoebas, suspended solids, organic pesticides, some heavy metals, bad tastes and smells. They will remove 99.99% of Giardia and Cryptosporidium. 

  • 98% Suspended Solids
  • 99.999% of Giardia
  • 99.999% of Cryptosporidium

    Particulate Reduction

  • 0.9micron>99.99%
  • 0.5micron>99.9%
  • 0.2micron>98%.     

Please note - Higher levels of chlorine, chemical contamination, or sediment, will slightly shorten the life of the filters.

Doulton Filter History

You may associate the name of Royal Doulton with fine tableware and figurines, but do you know how they came to have the word "Royal" associated with their name?

As early as 1827, Henry Doulton developed a ceramic filter to remove bacteria from the contaminated Thames River, to provide safe drinking water. In 1835 Doulton made a gravity fed stoneware water system combined with the ceramic filter, for use by the royal household. By 1862 with the advancement in microbiology Doulton created micro porous ceramic filters capable of removing more than 99% of bacteria.

The tiny pores of the ceramic filter known as depth filtration, make it extremely efficient at removing particulate matter and fine sediment. The tightly packed activated carbon will remove taste, odours and unwanted impurities through a process called adsorption. The ceramic wall of this filter has been impregnated with silver ions to prevent the growth of bacteria in the filter itself and also in the stored water. (The silver is not painted on the inside of the walls like other filters and will not disperse into the filtered water or wear out in 6 months.) Since the beginning of the century Royal Doulton has been a leading name in water filtration, world renowned for high guality and reliability.

For their achievements made in water filtration, Doulton was given the right to use 'Royal' in their name in 1902.
