As anyone whose tried filtering liquid with fine MHRB will testify, it's incredibly proficient at blocking the paper and reducing the flow to nothing.
My last extraction I made the tea in a pan, and after cooking left it to settle overnight. In the morning, I carefully made an indentation in the settled sediment and then put a coffee paper into the hole and let the tea fill it up, removing it with a ladle. Takes a little time, but works a charm and is infinitely faster than trying to gravity filter.
