  • AFM® Activated Filter Media is a direct replacement for sand, doubling the performance of sand filters without the need of additional investments in infrastructure. AFM® resists biofouling, biocoagulation and transient wormhole channeling of unfiltered water and never needs to be recharged or replaced.

    AFM® is a highly engineered product manufactured from a specific glass type, processed to obtain the optimum particle size and shape. It is then exposed to a 3-step activation process to increase its surface area by up to 300 times for superior mechanical and electro-static filtration performance.

    The activated surface of AFM® is self-sterilizing which prevents bacteria mud-balling, coagulation and channeling of unfiltered water through the filter bed. Activation increases the surface area by up to 300 times for catalysis and adsorption reactions. Similar to activated carbon, the surface nano-structure adsorbs pollutants from the water but unlike carbon, AFM® is recharged by just back-washing with water.

  • AFM® Activated Filter Media is a direct replacement for sand, doubling the performance of sand filters without the need of additional investments in infrastructure.

    AFM® is a highly engineered product manufactured from a specific glass type, processed to obtain the optimum particle size and shape. It is then exposed to a 3-step activation process to become self-sterilizing and to acquire superior adsorption properties.

    Self sterilizing surface: AFM® is 100% bio-resistant, prevents channeling and the biological conversion from urea to ammonia in the filter bed responsible for the toxic chlorine smells (trichloramines).

    Superior adsorption properties: : The surface area of AFM® is strongly increased and becomes hydrophobic (water-repellent) to filter particles down to 1 micron and to remove about 50% more organic substances from the water than sand and other glass filter media, thus reducing the formation of harmful THMs including chloroform by up to 50%.
