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 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-sterilizing and to acquire superior adsorption properties.
