Water Filter Gravity Fed


  1. Outdoor Recreation – Clean, healthy, great-tasting water from almost any fresh water source. For those situations where there is no reliable pressurised water supply, whether you’re at home, on a campsite, or in a holiday cottage, an SS gravity filter enables you to have clean filtered drinking water on tap.
  2. Emergency Preparedness – Providing safe drinking water to millions of people all over the world. Designed for emergency response as well as for use in short, medium and long term humanitarian relief situations such as refugee camps, natural disaster zones and community development programs.

Contaminant Reduction:

A recent study by a leading UK University showed that the use of Doulton drinking water filters in a community of Zimbabwe slashed cases of potentially fatal diarrhea (a common problem in Africa caused by pathogenic bacteria and cysts in the water supply) to virtually zero. Doulton water filters have been proven to work in the most demanding conditions.

The Doulton Stainless Steel Gravity Filter System (W9361123) uses 2 Doulton Super Sterasyl Ceramic Filter Candles which will reduce:

  • Pathogenic bacteria (Cholera, Typhoid, Salmonella, Serratia, E. Coli, Fecal Coliform)
  • Cysts (Cryptosporidium Parvum, Giardia Lamblia)
  • Sediment
  • Organic Chemicals (Pesticides, herbicides and organic solvents)
  • Metals (Lead, Iron, Aluminum)
  • Taste & Color (Hydrogen Sulphide, Iron, etc.)
  • Lead Removal: Lead is seldom found naturally in domestic water supply but can result from the dissolution of lead pipes which may still be in use in old water systems. The zeolite metal ion reduction medium in the Ultracarb element effectively reduces the lead content in drinking water.

Water Filtration Efficiency

The included SuperSterasyl (Sterasyl™) ceramic shell contains 0.2 microns silver which effectively removes pathogenic bacteria such as E.coli, cholera, salmonella, shigella, typhoid etc with greater than 99.99% efficiency, and 100% removal of pathogenic cysts such as cryptosporidium parvum, giardia lamblia, guinea worm etc.

The ceramic shell is packed with a bed of coconut shell granular activated carbon ( GAC) for removal of chlorine, VOC’s, industrial solvents, bad taste, odor, etc. For microbiologically effectiveness, the ceramic shell is self-sterilized (no need for boiling) and can be cleaned up to 60 times before is worn off.

Absolute filtration rating >99.9999% 0.9 microns absolute
Effective filtration rating >99.9% 0.5 – 0.8 microns
>99.7% 0.3 – 0.5 microns
>98% 0.2 – 0.3 microns
E.coli bacteria >99.99%
Fecal bacteria >99.99%
Salmonella typhi >99.999%
Vibrio cholerae >99.99%
Klebsiella Terrigena >99.999%
Shigella disinteriae >99.999%
Serratia marcescenes >99.99%
Cryptosporidium cysts 100%
Giardia cysts 100%

NOTE: It should be clearly understood that during tests performances the concentration of bacteria fed to the filtration element is artificially high in order to simulate a challenging test for the ceramic element. The most aggressive “real life” condition would normally be at least 1000 times less severe.
