After 3 years, finally bought a replacement. Our water is very good, so didn’t see a need for a filter.  However, the original one started showing signs of west and some strange growth that couldn’t be cleaned with the strongest of chemicals. My wife said either you or that filter is out of this house. Well, I like my house and love my wife so the search began for a new filter.  Alas, the stores don’t carry them, but the website does; I ordered two.  I calculate that will provide me another 4-5 years of wedded bliss and great coffee. Thank you Mr Coffee for bring joy back to our mornings.
