The Sawyer filter is a low-cost all-in-one water filter ideal for providing emergency drinking water.
Each filter comes in a sealed bag, compete with fittings for attaching to a plastic bucket and a diagrammatic instruction sheet.
It is possible for each Disaster Aid Response Team (DART) member to bring up to 75 Sawyer filters with their luggage on initial deployment.
A “build your own gravity system” can yield up to 90 litres of clean water per hour from any freshwater source, easily enough to protect a family.
The filter removes:
- 99.99999% of all bacteria, such as salmonella, cholera and E.coli.
- 99.9999% of all protozoa, such as giardia and cryptosporidium.
Typically the filter is attached to a locally purchased plastic bucket or any other clean unused plastic container by the attached hose.
As the water passes through the filter it can either be directed to a clean water container or someone can drink directly from the end of the filter.
