Advantages:
- The use of the filter does not require any energy
- Use of local materials (clay, wood fines)
- Easy maintenance: must be cleaned once a week. Do not put it under the sun otherwise seaweeds can grow
- Cheap ((sold for 30$ by Merinsa Company)
- Long lifetime: a few years
- Could be sealed (thanks to the plastic container’s lid) which prevents the water from being re-contaminated
Disadvantages:
- Use of silver (which is not always a material available locally)
- Use of an oven which should be able to reach 1000°C see if a potter around you has a ceramic oven and could lend it to you
- Heavy and bulky
- In our case, the price of the filter is low but still too high for the people in the slums who need it. Merinsa Company’s main clients for those filters are charities who then give them out to the families.
