Who We Are

We are a not-for-profit company based in the UK, engaged in the design and production of filters for clean drinking water. Inspired by the global need for safe water, our filters are currently being used in over 40 countries.

The filters are called the Grifaid® Family Filter and the Grifaid® Community Filter and they remove all biological pathogens down to 0.01 microns. They are designed to last for a minimum of 6 years, requiring no spare parts, cartridges, or electricity. They produce safe drinking water on demand, at a rate of 90 litres/hour and 300 litres/hour respectively.

How We Began

Building on earlier work by the Rotary organisation which has a long history of involvement in humanitarian aid projects in developing countries and in supporting emergency relief, Rotary district 1030 in the UK had been donating locally manufactured water filters to international NGOs operating in developing countries.

When Rotary appealed for assistance, local Rotarian John Griffith answered the call by volunteering his world-renowned skills in the field of engineering design. Working with Aquabox, another Rotary organisation involved in supplying emergency aid products, John successfully created new filter designs which met the requirements for a sustainable and environmentally friendly household water treatment solution to fit into emergency aid boxes.


The mission of this project was and still is based on a not-for-profit model, funded initially by charitable donations. But the design and development of the new filters would not have been possible without the financial support of a charitable trust set up by John and Gill Griffith following the sale of his business.

The next phase of the project is to ensure that the new filter designs are addressed to the widest possible range of market segments, so that a sustainable model can be established which will enable us to continue to support our charitable aims and objectives.

To get filters to people in developing countries who are in desperate need of clean drinking water, the continued support of all our donation partners will always be an important element in the successful achievement of our objectives.
