Description
Dryden Aqua AFM® NG Grade 1 Activated Filter Media 21kg
Upgrade your swimming pool filtration with AFM® NG Grade 1 Activated Filter Media from Dryden Aqua – the advanced alternative to traditional filter sand.
AFM® NG (Activated Filter Media Next Generation) is manufactured from recycled green and brown glass and activated using Dryden Aqua’s patented process to create a self-sterilising filtration media that actively resists bacterial growth and biofilm formation.
Designed as a direct replacement for filter sand, AFM® NG delivers superior water quality, improved filtration efficiency and lower ongoing operating costs.
Grade 1 media (0.4–0.8mm) is typically used as the top filtration layer and is engineered to capture finer particles while reducing channeling within the filter bed.
