AFM® Activated Filter Media is a direct replacement for sand and other natural filter media, 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 outlasts all other filter media.

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-sterilising and to acquire superior adsorption properties. During activation, the structure and the chemistry of the glass are modified.
