Product review (5 stars): Fits Thermador with 2.5X purifying capacity
I have an 18" Thermador freezer with ice maker/water purifier on the door. The filter that came with it was an UltraClarity that said "replacement element 9000 674655" and also said it was tested in models 9000 777508 and 9000 705475. This one fits and works fine. It is also the only one I could find that said it was good for 750 gallons. My original said it was good for 739.68 gallons (which strikes me as a tad over precise!) but most of the other filters I considered were only good for 300 gallons. That is a very competitive price to start with plus an additional 150% purifying capacity (2.5 X 300) compared to other filters.
