Dryden Aqua AFM Activated Filter Media

Dryden Aqua AFM Activated Filter Media

Result of 35 years of Research & Development, AFM (Activated Filtering Media) is a direct replacement for sand that can be installed in all types of sand filters without additional investment in infrastructure. Made from selected pure glass, AFM undergoes a unique activation process to become self-cleaning and acquire superior mechanical and electro-static filtration performance.

  • AFM is the most efficient filter media on the market with a certified filtration rate of 1 micron.
  • AFM is 100% bio-resistant: it prevents bacterial growth in the pool filter.
  • AFM is a sustainable product made from recycled glass

Your benefits at a glance

  1. Crystal clear water.
  2. Reduction of chlorine consumption
  3. No chlorine smell and up to 50% less THMs.
  4. The risk of infections by bacteria and parasites such as Legionella, Pseudomonas and Cryptosporidium is reduced to an absolute minimum.
  5. Same performance for many years. AFM lasts longer than all other filter media.

 HOW IS AFM MADE? SHORT VIDEO

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

Where can you use AFM?
