Active Filter Media - Grade 1 - 0.4 - 0.8mm


AFM® stands for Activated Filter Media, a revolutionary filter media made from green and brown container glass, developed by marine biologist Dr. Howard Dryden. AFM® exceeds the performance of quartz and glass sand by filtering at least twice as efficiently.


The catalytic properties on the surface of AFM® make it fully bio-resistant, which means no biofilm is formed in the filter bed. This reduces the chlorine demand and therefore the formation of harmful volatile disinfection by-products such as THM’s, cyanogen chloride and trichloramine.

Not only the chlorine smell but also the risk of getting infected by pathogens like legionella or cryptosporidium, is greatly reduced. The pool is healthier, especially for children, safer for the environment and more economical.
