FFCC's Impact H2O program installs filters designed by SAWYER Products which use an improved version of membrane filtration technology. Derived from filter systems used for kidney dialysis, SAWYER biological filters use tiny tubes with micro pores. Water is able to flow through the micro pores but larger particles like  bacteria, protozoa, or cysts like E. coli, Giardia, Vibrio cholerae and Salmonella typhi (which cause Cholera and Typhoid) are trapped by the filter. When contaminated water is flushed through the filter,

 99.99% of particles >0.1 microns are removed. Once installed, the filter can process 5 gallons of water in 10-15 minutes. When the filter gets clogged with trapped particles, it is easily back-flushed using previously cleaned water. This process takes only a few moments before the filter is up and running again.  

FFCC volunteers team up with local community members to install filter kits which include the filter, tubing, fittings and a water bucket. Installation and demonstration is usually done in the home or clinic where the filter will be used. The recipients are instructed on how the filter works, proper use and storage, and how to maintain and back-flush the filter. This includes "hands on” practice with the recipient before the installation is complete. The whole process takes about 1/2 hour and the filter can be put to work immediately. Follow up visits are done by local volunteers at 1 week, 1 month, 6 months and again at 1 year. This allows FFCC to ensure the filter is working and being used properly. These visits also provide information from the users about changes in their health, filter effectiveness and any problems they may be having. It is through these follow-up visits that FFCC sees first- hand the success of the Impact H2O program and documents how clean water changes lives.


FFCC takes pride in building long-lasting relationships with the local people. When a U.S. FFCC team leaves a project area, trained local community members remain. These local teams are available to answer questions, conduct filter follow up visits, troubleshoot filter problems, and install additional filters. Local teams work with FFCC everywhere we take on a project. They are invaluable to the success of the Impact H2O program.
