AFM® Activated Filter Media

AFM® Activated Filter Media is a direct replacement for sand, doubling the performance of sandfilters 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.
