Bosch Recommended Filter Review by John The Consul
I use this filter in my Bosch refrigerator. It is the filter recommended by Bosch. You can operate the water dispenser without a filter, but this one does a fine job of improving taste and quality of the water and ice. (Posted on 8/31/08)
Proprietary ! Review by Boschfan
We think very highly of the Bosch line of appliances, yet it baffles us that they rely on a proprietary, unique water filter. Cuno makes it for Bosch, and the identical filter can come in a Cuno box (white, pictured) or a Bosch box (blue, with graphics).

No directions come with the filters.... (Posted on 2/15/09)

Good product Review by Charlie
This is my second order for this filter, required for our Bosch refrigerator. Works perfectly, easy to replace. (Posted on 7/12/09)
