The Doulton®
water filtration systems are the original gravity-fed water
purifiers, and have been used since 1827. |  |
You've probably heard of the "British Berky" water systems,
sold on many websites. They are simply copies of the original Doulton systems.
In fact, the "new" Berky systems are not only NOT made in England, but
they now use a lower quality black filter, which can't be cleaned and reused (like
the original Doulton ceramic filter), but the black filters preform no better
than filters you can buy at Home Depot!

Doulton®
water filter systems are especially designed to micro-filter a supply of
safe drinking water from cisterns, ponds, streams, and other sources of questionable
water. These very reliable filters are manufactured to the highest grade available
in the world. They are corrosion resistant, hygienic, durable, and easy to clean.
Doulton® water
filters are also compact, portable, and simple to operate. Requiring no external
plumbing, each filter takes only minutes to assemble and can provide up to 24
gallons or more of safe drinking water each day. The high-tech silver-impregnated
ceramic elements feature a nominal filtration efficiency of : 0.2 microns,
greater than 98%, at 0.5 microns, greater than 99.9%, and at
0.9 microns, greater than 99.99% which effectively blocks waterborne
pathogens and clarifies the water.
These
filters are in common everyday use in households across the world, and are particularly
effective on private well systems. Their replacable filter elements have an activated
carbon core and are designed to remove undesirable tastes, odors, and many organic
chemicals.
The ease of operation
combined with a proven effectiveness at eliminating water-borne diseases such
as cholera and typhoid has led to the filter being the preferred unit for field
operations by many of the world's major aid and emergency relief organizations.
- Produces safe drinking water
from lakes, cisterns, streams, etc.
- Reliable
design uses gravity — no pumps to wear out
- Long
lasting filter elements will filter up to 60,000 gallons (using four elements),
depending on turbidity level of the water being filtered and proper care of the
filter elements
What
the filter will remove
- Absolute
filtration efficiency to 0.5 microns (U.S.)
- For
particles 0.2 microns, efficiency is greater than 98%; from 0.3 to 0.5 microns,
filtration efficiency is greater than 99%
| E.Coli | Greater
than 99.99% |

How
the filter works
The special
ceramic elements are manufactured specifically for use in this gravity filter.
Doulton® ceramic elements consist of a fine microporous structure, which forms
a complete barrier to all particles larger than 0.5 microns in size (1 Micron
= 1/1,000th of a millimeter). All particles above this size become trapped on
the surface and within the ceramic material. Fine particles of silver are evenly
dispersed within the structure of the filter element, which prevent the growth
of bacteria (mitosis) within the ceramic wall. The Doulton® elements also
contain an additional activated carbon filling, which removes chemical and organic
compounds from the water and improves its taste and odor.
After
passing through the filter elements, safe, filtered water then collects in the
lower chamber to be drawn off from a tap. The structure of the ceramic material
is designed to be cleanable and regular cleaning of the element will
allow its filtration efficiency to become regenerated. The elements may be cleaned
over 100 times before replacement becomes necessary.
