Quality and purity

FILTER COAL H complies fully with the following standards and regulations:

  • EN12907
  • German Drinking Water Ordinance 2023
  • DIN 19643
  • DVGW work sheet W 213
  • ÖNORM 6216

Chemical and physical characteristics

Carbon approx. 88 %
Ash6 - 9 %
Volatile matter 2 - 3 %
Specific density approx. 2.0 g/cm³
Bulk density approx. 500 kg/m³
Specific surface area (BET)approx. 300 m²/g


FILTER COAL H is used as the top layer in dual media filters. It is particularly well suited for swimming-pool water treatment by removal of disinfection byproducts such as chloramines, trihalomethanes and adsorbable organic halogen compounds (AOX). Degradation occurs by adsorption as well as catalytic decomposition on the media's phase interfaces.
