Dryden Aqua AFM® Activated Filter Media is a premium alternative to conventional silica sand, engineered to deliver cleaner water, improved filtration performance and a longer service life. Manufactured from recycled green and brown glass bottles, AFM® undergoes a unique three-stage activation process that transforms the glass into a highly efficient, biofouling-resistant filter media capable of significantly outperforming traditional sand.

Unlike standard filter media, AFM® resists bacterial growth within the filter bed, helping to eliminate clumping, channelling and the formation of biofilm. The activated surface provides exceptional particle capture, removing fine contaminants while maintaining excellent hydraulic performance. The result is crystal-clear water, reduced maintenance requirements and lower operating costs through less frequent backwashing and reduced water, energy and chemical consumption. AFM® is independently verified to provide up to double the performance of traditional sand filtration and has an expected service life of over 10 years.

Our range includes both Grade 1 and Grade 2 AFM® media:

• AFM® Grade 1 is the primary filtration layer used in most swimming pool and spa sand filters. With a particle size of 0.4 to 0.8 mm, it provides outstanding filtration efficiency, capturing extremely fine particles while maintaining excellent water flow. It is the main working media responsible for delivering superior water clarity.
  
  
• AFM® Grade 2 features a coarser particle size of 0.7 to 2.0 mm and is typically installed as the support layer beneath Grade 1 in multi-layer filter beds. It promotes even water distribution, protects filter laterals and enhances the overall performance and efficiency of the filtration system.

Whether you're replacing traditional filter sand or upgrading an existing system, Dryden Aqua AFM® offers a proven, environmentally responsible filtration solution trusted in domestic pools, commercial facilities and water treatment applications worldwide.
