Product review (4 stars): The Bosch Refrigerator manual says the water filter is 9000 ...
The Bosch Refrigerator manual says the water filter is 9000 077 104 but the box for the replacement filter I got from the retailer where we bought the unit says the filter is 9000 194 412.  So, I searched for both filter numbers and this filter is available for less $$.  Does anyone know if there is a difference in these filters (they both say they are made by Bosch)?  Also, the Bosch website says the filter they are  selling for our refrigerator is 00740570 (or BORPLFTR10).  If all the model numbers are for the same basic filter for different years of production do the older models lose their effectiveness the longer they are unused?
