AFM®   is the only Active Filter Media  it is not a basic crushed glass product   click here for performance and  health & safety issues

If its not AFM® its not Activated

AFM® is an Activated Filter Media, manufactured and activated by Dryden Aqua under ISO procedures  to have  a high negative zeta potential and catalytic self sterilizing properties.

AFM® is manufactured from reprocessed glass, but it is not a basic crushed glass filter media..  We have a basic crushed glass filter media product available for low end applications.  AFM® is a highly processed product  which has been tested by independent UK Government laboratories and the water industry and has been certified safe for all water filtration applications.  Filter sand has by-passed the regulations because it was in use before the regulations were in place. However man made filtration products are not exempt, and AFM® is the only filtration media that is in compliance with the regulations and is safe to use for applications such as drinking water, swimming pools and aquaria..  A basic crushed glass product does not have the surface active properties, there will be a hydraulic lenses effect which leads to channeling,   there are also serious health implications for the public and contractors from using a basic crushed glass product.  Dryden Aqua have completed a 1.2 million Euro Research Project in co-operation with the European Commission under the Life Environment initiative to solve these problems.

What is AFM®

AFM® is an activated filtration media manufactured by Dryden Aqua.  In addition to the product applications and process technology have been developed by Dryden Aqua.   AFM® is engineered to have surface active properties of adsorption and catalysis as well as acting as a mechanical filtration media. AFM® is a great deal more than a recycled glass filter media.
