AFM® Activated Filter Media is a direct replacement for sand, doubling the performance of sand filters 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.
AFM® benefits at a glance:
AFM®has been independently tested by IFTS Institute de la Filtration et des Techniques Séparatives in France in 2014 and its superior performance over quartz sand and other glass filter media was confirmed and is documented in the 2014 IFTS Report available below. AFM® more than doubles the performance of a quartz sand filter and it performs multiple times better than all other glass filter media tested.
