Yellowish Groundwater? AFM® Can Truly Solve the Iron Problem

The Common Issue: Yellow or Metallic Groundwater

Groundwater is a widely used water source in homes, resorts, and factories because it’s easily accessible and low-cost.
However, a common problem many people face is yellow-colored water or a metallic smell — caused by dissolved iron (Fe) and manganese (Mn) in underground water.
When exposed to air, these elements oxidize and form iron rust particles, resulting in yellow stains, odors, and clogged filters.

Why Conventional Filters Can’t Completely Solve It

Traditional filters that use sand or standard glass media can improve water clarity but can’t effectively remove dissolved iron and manganese.
The smooth surface of sand particles has large pores, making it prone to clogging and bacteria growth over time.
As a result, the water becomes cloudy again shortly after filtration, and the system requires frequent cleaning or replacement.

AFM® – The Premium Glass Filter Media from Switzerland

AFM® (Activated Filter Media) is an advanced filtration material from Switzerland, specially engineered to outperform conventional sand and glass filters.
Each grain is activated to create a permanent negative charge that attracts and traps fine particles, metals, and organic matter more efficiently.

Key Advantages of AFM®

  • ✅ Removes up to 95% of iron and manganese

  • ✅ Inhibits bacteria and biofilm growth

  • ✅ Eliminates metallic and chlorine odors

  • ✅ Lasts up to 10 years without replacement

  • ✅ Ideal for groundwater, swimming pools, and recycled systems

Real Results: Before and After Filtration

In real case tests, AFM® successfully transformed yellowish groundwater into clear, odor-free, and safe water — even when iron levels were high.
