Description
Result of 35 years of reseach & development, afm® (activated filter media) is a direct replacement for sand that can be installed in all types of sand filters without modifications.
Manufactured from green and brown glass, afm® is exposed to a unique activation process to become self-sterilizing and acquire superior mechanical & electro-static filtration performance.
