Carbon Filter

A carbon filter uses activated carbon to remove impurities, chemicals, and odors from water through adsorption. In water heating systems, it helps reduce chlorine, VOCs, and other contaminants that can contribute to scale buildup or corrosion, protecting equipment and improving water quality.

💡 Key Takeaways

  • ✓A carbon filter uses activated carbon to remove impurities, chemicals, and odors from water through adsorption. In water heating systems, it helps reduce chlorine, VOCs, and other contaminants that can contribute to scale buildup or corrosion, protecting equipment and improving water quality.
  • ✓Filter performance depends on flow rate and contaminant levels.
  • ✓Carbon filters reduce chlorine and VOCs but do not remove dissolved minerals.
  • ✓Water testing helps determine the right filter type and change interval.
