Spelling of the carbon material name is incorrect --- Anthracite literally "a type of coal", is a hard, compact variety of mineral coal that has a high luster.

 

You will be looking for high luster and uniform sizing - you need to contact the manufacturer of your system to get the best match.


Sincerely,

Many other types of filter media are available (for example anthracite, birm) depending on the type of water treatment desired.

Water processed by any filter requires further purification or disinfection before it can be considered to be safe drinking water

Hi All,

Thus we conclude the use of Anthracite (or any other relevant alternative in filtration process) seems limit the scope to a quality point rather than a safety control (?)...

I'd personally still be inclined to ensure that the anthracite is a suitable food grade in terms of impurities, or absence thereof. My understanding is that there is potential for coals to contain various heavy metals and also some radioactive isotopes, and so not ideal for food use!
