Really good point. Thank you for the link!

Hi Bettina! Here are some answers:

- Are there any products like this already in use? There are examples of jerrycan filters that can be bought as a full product - not to an existing jerrycan. Our outlook was that we should design a small filter that incorporates with what they already have/use on a daily basis.

- Will you be able to create one of your designs to test it out? We are in the process of developing and making a final product that functions well mechanically. The filter element has largely been built from research: video demonstrations, case studies, scientific explanations and physical properties. We're certain the filter works, its figuring out the flow rate and how long the filtration process may take.

- How do you know it will be affordable? We've kept affordability in mind during the process. We're aware that it is a major factor in the success of the product. The piece itself is quite small. We've narrowed the form to 3 pieces for injection mold. The materials (porous ceramic, plastic, mesh, and rubber) are all inexpensive and require small quantities of each. In theory, at a high rate of production (potentially in Asia) the model should come to a cost projection of $1 at the most (50c at best).

- Will the water be clean enough to drink and if so how do you determine that?
Good question. the choice of porous ceramic was long process. Ceramic has shown to remove bad bacteria, viruses, bad tastes and odors well. It does remove small sediments but can be prone to blocking if the sediment is too large which is why we've implemented a mesh filter that is used prior to the ceramic filtration.

Guy: Depending on the success of the product, Unilever are interested in prototyping the real thing which would be a major step forward. We're currently researching into distribution methods. Do you have any suggestions?

We see this product as a cheap solution that is a major step forward in cleaner water with greatly reduced cases of illness to keep children in schools and for parents to continue their daily work.

Really good questions Bettina & Guy, it's really important that we're able to answer these key questions and that the product reflects that. If you have any further comments or thoughts on my answers, please do so! :)

Hi Guille, sorry for the late response!

I really like your point about the water collection process as a social platform. It is really important! I recently read a case study on the Hippo Roller product on site in African countries. The product was popular to the extent that it encouraged men to join in on using this piece of equipment for collecting water.
The unforeseen downside was that exact point you mentioned - it stripped away that time women spent with one another. We'll definitely keep this in mind going forward.

Regarding their resources, we see massive benefit from designing something that could bee locally produced. We believe it would encourage self- sufficiency and maintenance. But as you probably know it has a lot of unknown variables such as quantity and quality of resources vary between villages. Without going over for first hand research, we'd be risking in designing a product that has been based off of numerous assumptions.

What do you think?
