AFM is not recycled glass or sand!
Difference from other glass media on the market:
Activation – During the production process, raw AFM® undergoes a three-step chemical and thermal activation process. Activation is the reason for its bio-resistance and amazing filtration performance.
Raw material – We only use green and brown glass because white glass does not contain the metal oxides necessary for activation. Green glass and brown glass carry a charge which is greatly increased upon activation.
Production – Dryden Aqua is a manufacturer of glass filter media – other competitors are glass recycling companies who sell their “waste”. Our production is probably the most sophisticated and sustainable glass processing plant in the world. We have optimized each part to produce the best material available, with the best shape and size for our applications. We ensure that our product does not have any sharp edges that could hurt you or damage the filter.
Efficiency – Thanks to the points mentioned above, we are able to produce a material that filters particles 20 times smaller than sand or any other competing product. This is proven by the independent laboratory IFTS in France
AFM of : Filters 95% of all particles down to 1 micron.
Sand : Filters 95% of all particles down to 20 microns.
recycled glass : Filters 95% of all particles >25 microns
