Discover the unique 100% bio-resistant and world's best performing filtration media

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 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.

unique benefits

Fully prevents bacterial growth, biocoagulation and channeling in the filter bed
Provides exceptional water clarity: Certified 1 micron filtration (w/o flocculation)
Delivers stable filtration performance and outlasts all other filter media
Certified for pools, potable water use (NSF 50/61), food & drinks markets (HACCP)
Prevents the formation of harmful disinfection by-products (THMs, NCl3)
Significantly lowers chlorine oxidation demand
Attracts and removes heavy metals, organic matters and microplastics
Offers substantial water and energy savings thanks to shorter and slower backwashes
