A SIMPLE WATER FILTER USING LOCAL RESOURCES.
moringa seed filter – product design
As the Moringa tree grows in Nepal, it's seeds can be a feasible option to purify water in that
coutry. The Moringa seeds, which can be extracted from the pods have to be dried and crushed before
putting them in the moringa seed filter. The filter is a small device consisting of two parts, wich
can be screwed together, allowing the cleaning of the filter as well as the changing of the seed
powder easily and quickly. Three sieves control the flow rate of the water, giving the seeds enough
time to absorb harmful bacteria. The filter can be screwed to jerry cans and with an adapter it can
be screwed to regular water bottles which are easy to find in Nepal since there is no bottle return
service. The moringa seed filter can be carried around due to it's small size and is therefore also
inexpensive to produce. The only additional part Nepalese people would require, is the Moringa tree,
which is a sustainable resource and whose parts can also be used to help with malnutrition and
