Review on OptiCharco Filters: The Ultimate Keurig Replacement by Chef Deane

A neighbor gave me her kereg which no longer worked. He made a loud noise and no water came out. Cleaned with vinegar and x20, still nothing. Then I noticed that the filter is not installed and there is some slime where it goes. I went downstairs with a bottle brush to remove hardened mucus. I ran V and h20 and it worked. No loud noise! She said she doesn't use filters because she can taste charcoal. (Had she run the water through the filter "before" installing it, she probably wouldn't have tasted anything. How can you taste charcoal with city water, coffee, 1/2 and 1/2 and sweetener? I use Multi - Pure Filtered Water And these filters She can afford a new kerug every year, I don't want to.
