The FairCap Project

by mauricio in Design

Barcelona, Spain

Over 1.5 million people die every year from drinking contaminated water. Imagine if you could get a portable tiny water filter that could be screwed into any plastic bottle which would allow you to safely drink any available water, from a stream, from a lake, from a water pond? Imagine what it would mean for a poor family in Africa to be able to get this filter for just $1?

We already have a working prototype and we would like to launch this collaborative funding to prove that open projects can solve important problems in the world!


The FairCap project is an open initiative, please share this with your friends and join us! You can contribute to the project financially by pre-ordering one of the final prototypes, donating to the project, donating Faircaps to NGOs and by volunteering your time and skills to make this happen!

Right now we are in the process of ordering the manufacturing of the filters from third parties, this will allow the project to become a reality without the need of large funding.

We need around 5,000 to 10,000 euros to fund the first production run, we believe we can all together fund this amount and keep the project moving forward. The initial cost of the filters will be between 5 and 15 euros, but with your help we hope to drop the cost of the most basic filters close to 1 euro during the next year . We have changed the end date of this project from April 2016 to October 2016, we hope to deliver the first Faircaps by then. DEADLINE UPDATE: APRIL 2018 after much work on the redesign to optimize costs and finding the right lab to make the membranes, we have received the first final products. We will conduct testing and start shipping to all our supporters by July 2018. All the funds are on our Paypal account and can be refunded if you wish to due to this delay, they will only be spent once we finalize the production details. We take your contributions very seriously and thank you for your continuing support.

    Transparent design

    We wanted to openly ask the community what everyone thought of designing the final FairCaps with a transparent material so that everyone would be able to know what's inside the filter and how it works. We think this would be original since other filters in the market are closed "black boxes" and it's impossible to know what's inside. Any comments?
