Query: KF550 filter?

Is this the filter for the braun KF550? Who knows? Amazon sure doesn't seem to. The virtually worthless Braun product manual doesn't say either. Why is it that Amazon concerns itself with recommending to me music based on what I bought in March 1999, but can't be bothered to recommend to me an expendable filter for the coffee pot I bought in February 2005?
