Questions and Answers
Can a filter this small and inexpensive really generate clean, safe water from highly contaminated water?
Yes. See our product description page.
How does the filter work?
ceramic filter is filled with silver–impregnated carbon, preventing
bacterial contamination through mitosis, while creating a hostile
environment for microbiological organisms. It has a filtration
efficiency of 0.2 micron. This is sufficient to filter cholera and other
water-borne bacterium. This is a gravity-operated system with nothing
to plumb and no electricity needed.
How do I maintain the filter?
ceramic element itself can be cleaned with a damp cloth or soft brush
five or six times a month if necessary up to 100 times or more. There is
nothing to back-wash, and no cartridges to replace. To prevent packing,
the filter element may be shaken from time to time. For more detailed information about taking care of your filters, check out our article How To Maintain Your Ceramic Filter.
Is the Filter hard to assemble?
Part of the beauty of this filtration method is its simplicity and
portability. The filter is small and light-weight. All you need are two
same-size plastic buckets and something sharp enough to cut plastic.
Putting it all together is simple. Instructions are included with the
filter. Click here to view detailed, step-by-step assembly instructions.
Are instructions available in other languages?
Yes. Currently assembly instructions are available in English, Spanish, and Haitian Creole.
What about the flow rate? A 0.2 micron filter is really small!
are right. A 0.2 micron filter is really small. However, the tiny pore
size is necessary to remove cholera and other nasty little critters.
Even so, a gravity-fed system should produce a flow rate of up to one
gallon of clean water per hour. Check out our Lab Reports page for information about the filter's effectiveness!
I am not involved in Humanitarian or mission work. Would this filter be right for me?
filter will provide higher quality water than most water pitchers and
bottled waters. However, if two plastic buckets stacked atop one another
on your kitchen counter clashes with your kitchen décor, you may want
to select an under-the-sink model for daily residential use. We believe
our ceramic filter should be part of every home’s emergency kit. This is
especially true if you live in a coastal area where water is routinely
stored for hurricane preparedness.
How long does the filter last?
the ceramic filter is used to purify a municipal source, it should be
efficient for a minimum of one year. If you are using it to filter water
from rivers and streams or in disaster or third-world environments,
the longevity will be relative to the contaminant level of the water
source but should be reliable from six to eight months when cleaned
properly. Proper care of the filter will increase longevity. This
includes the use of a pre-filter, keeping the ceramic element clean and
shaking the filter occasionally to prevent packing.
Is there anything else that I have to buy to make these filters work?
must have two same-size plastic buckets, and something sharp enough to
cut plastic. FDA-approved food-safe buckets are recommended. For more
information on food-safe plastics, see our page Selecting Buckets For Your Water Station.
For ease of use, we recommend the spigot. The sock is not essential to
the process if you are filtering a clean water source. In addition to
this you’ll only require water and gravity and you’re in business!
Flying into disaster areas with a load of buckets doesn’t sound like fun. Must I take the buckets?
You can easily find plastic buckets in a third world country. Municipal
water sources are few and far between. Therefore buckets are sold in
villages everywhere so that the average person can fetch water from any
water source within walking distance.
I want to take these filters to _______. How should I transport them?
should be determined by the recipient country and the quantity of
filters to be transported. Individually boxed, these filters can fit
into a standard suitcase and be checked as baggage. If you are
purchasing filters for a specific country and need information about
getting them there, contact us. We will do what we can to help.
We want to take water filters with us on our next mission trip. Will we have to pay duty on the filters?
is an important question. Sometimes the answer is not set in stone,
regardless of what one is told. In countries suffering in the aftermath
of a disaster, items brought in, or sent in for disaster relief often
qualify as “duty-free.” If you are serving and assisting an established
organization in the country you are visiting, ask them to inform you and
to help you clear customs. We are here to answer any questions we can.

just want a filter to keep at home and at work “just in case.” How long
can I store the filter if there are no disasters for many years?
hope you never need our filter to survive a disaster. But if you do, as
long as the filters remain dry, they will be there for you for decades.
You’ll never buy peace-of-mind this cheap. Check out our page Storing Water Filters For Emergencies for more information.
