AFM®
Activated Filter Material
What is AFM® ?
- AFM® is the best performing filter media on the market with a certified 1 micron filtration rate.
- AFM® is 100% bio-resistant: Prevents bacterial growth in the filter bed.
- AFM® is a sustainable product made of recycled glass.
Your benefits at a glance
- Crystal clear water.
- Lower chlorine consumption.
- No chlorine smell and up to 50% less THMs.
- The risk of infections by bacteria and parasites such as Legionella, Pseudomonas and Cryptosporidium is reduced to an absolute minimum.
- Same performance for many years. AFM® outlasts all other filter media.
AFM® - The best filtration requires the best filter media!
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® 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 become self-sterilizing and to acquire superior adsorption properties.
Self sterilizing surface: AFM® is 100% bio-resistant, prevents channeling and the biological conversion from urea to ammonia in the filter bed responsible for the toxic chlorine smells (trichloramines).
Superior adsorption properties: : The surface area of AFM® is strongly increased and becomes hydrophobic (water-repellent) to filter particles down to 1 micron and to remove about 50% more organic substances from the water than sand and other glass filter media, thus reducing the formation of harmful THMs including chloroform by up to 50%.
AFM® is not glass sand!
Difference to other glass media on the market:
-
Activation - During the production process the raw AFM® goes through a three-step chemical and thermal Activation Process. The Activation is the reason for it's bio-resistance and its amazing filtration performance.
-
Raw Material - We only use green and brown glass because white glass does not contain the metal oxides necessary to be activated. Green and brown glass carry a charge that is strongly increased during the activation.
-
Production - Dryden Aqua is a manufacturer of filter media made of glass - other competitors are glass recycling companies that sell their "waste". Our production is likely the most sophisticated and sustainable glass processing factory in the world. We optimised every part to produce the best material available, with the best shape and size for our applications. We ensure that our product has no sharp edges that can injure you or damage the filter.
Efficiency - Due to the mentioned points we are able to produce a material that filters 20 times smaller particles than sand or any competitive product. This is proven by the independent laboratory IFTS in France:
For a high performance, healthy, ecological and economical pool water treatment
Proven in more than 500'000 pools around the world!
