I have Berkey also, with two black filters. I think it is very good filter , and not too much work to keep it clean and running....i just cleaned it 2 days ago and also rub the filters and the water flows again pretty good.
Only issue is that the plastic screws in the black filters are slipping when i put the filter back...i read somewhere that some put ptfe tape to the screw part, so i put some there and it helped . I wish the screw part was stainless steel and made better .
