The technology of the water filter is
simple, effective, and, sustainable. A
round-bottom ceramic pot is made from a
mixture of clay, a combustible material
(sawdust or rice husks), and colloidal
silver. The colloidal silver is a naturally
occurring anti-bacterial which improves the
bacteria removal rate for the filter. First,
the clay and combustible are mixed with a
measured amount of silver and water until a
homogeneous mixture is formed.
 The
mixture is made into a filter and kiln
fired, burning out the combustible material
and leaving micro pores coated with the
silver to clean the water. During the firing
process, about ˝ inch of charcoal is
produced within the filter to improve taste
and color. The filter, which is designed
with a rim, is placed on a five gallon
plastic storage bucket with a spigot at the
bottom for dispensing.
|
A lid is placed on the filter to prevent
contamination. When used, water is poured
through the ceramic pot and filtered into
the receptacle bucket. Safe drinking water
is easily poured from the spigot by all
members of the household.
The flow rate of the filter ranges from 20
to 30 liters per day depending upon how
often the filter is refilled. Filters are
cleaned by lightly scrubbing the surface
when flow rate is reduced, and it is
recommended that the filter is boiled every
three months to insure optimum
effectiveness. The effective useful life of
the filter is at least 5 years.

Because our filter design and the manufacturing process are
proprietary (and patent protected),
we are unable to answer technical
questions on these topics. However,
we do try to help with general
advice and educational materials on
a limited basis when possible. Some
further assistance and consultation
may be available on a daily fee
basis.

The FilterPure® filter is fabricated to have an actual pore size
of 1.3 microns and has been measured
to have an effective pore size of .9
to 1.1 microns. This filters out
turbidity, bacteria and protozoa.
The added colloidal silver renders
any remaining bacteria ineffective
as it passes through the ceramic
membrane. One half inch of activated
charcoal is fired into the filter
core and improves odor, taste, and
color. All in all, the FilterPure
filter removes up to 99.99% of
pathogenic bacteria and oocytes
while it retains healthy,
naturally-occurring minerals. |

Other organizations produce or support the
production of ceramic water filters for
third world application.
But, FilterPure is different:
■
The FilterPure filter was designed to be
produced and used in a third-world
environment, using commercial grade
technology to produce high quality,
reliable yet low-cost filters.
■
Filter quality is maintained through
on-going testing.
■
FilterPure also conducts strong training
programs for filter maintenance and
community hygiene.
■
FilterPure partners with local NGOs and
organizations to deliver more filters to
more people.

Other producers make water filters which are
different .. in look, design and operation.
Some have a different shape and use
different materials. ALL use a different
production process. While most will work
well for a while, they normally have a much
shorter useful life than the FilterPure
filter.
In addition, the ongoing maintenance of
these filters is typically much more
difficult. We have found that, if a filter
isn’t maintained properly, it won’t work. If
the filter isn’t working, the users won’t be
protected (and may not realize it!)
The FilterPure filter was designed to be
produced and maintained in a third world
environment. Both the production process and
ongoing maintenance procedures are designed
to be “fool-proof”. Simplicity in design and
maintenance, as well as providing a long
useful life, were primary goals. |
