AFM® Grade 0 is the finest grain activated glass filter media offered by Dryden Aqua. With a particle size of 0.25–0.50 mm, it provides exceptional micro‑filtration performance, capturing particles down to less than 1 micron. Designed for polishing or top layers in multi‑grade beds, this media improves water clarity, reduces chlorine demand, and resists bacterial growth. A 25 kg bag is ideal for high‑specification pools, drinking water systems, and other filtration setups requiring ultra‑fine filtration.
