AFM® NG Grade 2 Glass Filter Media – 0.7‑2.0 mm (25 kg Bag) NSF Certified

AFM® NG Grade 2 is an advanced, activated glass filter medium engineered by Dryden Aqua to offer superior performance over conventional filter sands. With particle sizes between 0.7 and 2.0 mm, this media acts both as a support layer and a filtration layer, capable of removing particles down to approximately 5 microns. Its unique activation process ensures bioresistance, reduced chemical demand, and consistent filtration performance over years of use.

• Key Features

• Particle size: 0.7‑2.0 mm (Grade 2 NG)
• 25 kg bag — enough for a standard medium‑rate sand filter bed or partial replacement
• Made from recycled green/brown soda‑lime‑silica glass, activated to resist biofouling
• High sphericity and tight uniformity for optimal flow and efficient backwashing
• Certified performance: removes particles at ~5 µm, significantly finer than standard sand filters
• Bulk bed density approx. 1.40 kg/L (uncompacted)

✓ Benefits

✓ Clearer water through finer particulate removal
✓ Reduced backwash volume and frequency — saves water and cost
✓ Lower chemical usage due to better filtration and stable media behavior
✓ Long lifespan when properly maintained — activated glass resists degradation
✓ Compatible with existing sand filter equipment (same volume loading)
