$1 Water Filter Project

Percent of all water in the world is drinkable
Billion people without clean water
Million Deaths from contaminated water
Billion infected people every year

"Water is the operating system (OS) for life, without clean water we would not be able to survive. Clean water technologies should be shared and open sourced, to innovate on design and make them accessible for the people who need them most."

HIF grantee 2016

Selected by the Humanitarian Innovation Fund to research, design, produce, test and implement the Faircap filter project.

Oxfam Partnership 

As part of the HIF grant we partnered with Oxfam International to get advice, support and test the Faircap filters.

UN WHS Innovation

Selected to present at the United Nations World Humanitarian Summit in Istanbul 2016 as part of the humanitarian innovation hub


Open source. Collaborative. Shared.


Low Cost. Affordable. For the people.


Simple. Innovative. Effective.


Over 1.8 million people die every year from drinking contaminated water and 4 billion disease cases are reported each year causing a huge health and economic impact. Water sources are becoming scarce and being contaminated more and more not only with bacteria but also with chemical residues from households, agriculture and industry. Even in rich countries the public’s trust in tap water has been affected, creating yet another environmental problem due to the disposal of plastic bottles.

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 source, from the tap, from a stream, from a lake, from a water pond? Imagine what it would mean to get this filter for just $1?

Open Source Collaboration

We have a working prototype ready and we need your help to make the Faircap filter as low cost and affordable as possible. You can help us scale the project to produce millions of FairCaps. Soon we will be producing the first finished products and you will be able to order some and help us achieve this goal. Sign up to get more news about project!

If you are a designer, engineer, microbiologist, university student, professor or would like to become an ambassador and help us promote this vision please join the project and help us out with your skills.

From a restorer of cultural heritage to industrial designer, this is where I found my true vocation. My main motivation is the search and application of practical and profitable solutions towards products or waste design. Maybe that's why for me it's a pleasure to have the opportunity to collaborate with the Faircap project; a kind of project whose main motivation is to contribute a grain of sand to create a better world.

Eco-Builder, an engineer and a 3d Artist. I love to build. Building is for me the perfect balance. It makes you feel complete. It incessantly makes you go from design to matter, from bits to atoms, back and forth, all the time. if we really hope for a peaceful world, everybody must first be able to provide for their vital daily needs, stresslessly : water, food, shelter. I’m developing the Fabship project. A FabLab in an Earthship.
