The filters are very expensive and they’re not third party verified the way every reputable filter is. For unknown reasons berkey only puts out their own data that magically shows their filter to be the best in the world but won’t do industry standard testing.

We used to have one and got rid of it both because we don’t trust the company and because even with hard water the filters didn’t get clogged. We ran the same water through a basic sawyer squeeze filter and it needed frequent back flushing. People have even shown that berkey black filters cause dissolved solids in the water to increase.

Something to think about - those $170 filter sets are completely hollow. They’re made to look like a nice solid filter when they’re not. They’re not even a thick filter with a hollow core, they’re maybe a 1/2” thick around the edge and the rest of what they’re selling you is air with a plastic base glued on.

A Sawyer or other backpacking filter will serve you better and is much less expensive. For home base sort of use the family or mission lifestraw filters are a good option.
