Product Overview

This is a carbon-based refrigerator water filter for the dispenser and ice maker of select Bosch refrigerators. It reduces chlorine taste and odor, rust, and sediment, so water and ice look and taste cleaner.

Please note: Frostwaterfilter is an independent retailer. This filter is a compatible replacement, not made or sold by Bosch, Thermador, Gaggenau, or Cuno. Those names appear only to identify the refrigerators and part numbers it fits.

Will This Filter Fit My Refrigerator?

It fits Bosch refrigerators that use the UltraClarity REPLFLTR10 filter, mostly the Evolution-series and similar models. Find your model number on the rating plate inside your fridge and check it below.

Models often carry suffixes like /01 or /02. These normally belong to the same fridge.

Part numbers this filter matches: REPLFLTR10, BORPLFTR10, REPLFLTR30, BORPLFTR30, 11034152, 11034151, 644845, 9000 077104, 9000194412, 740560, 499850, RA450010, RA450021 (Gaggenau).

⚠️ Don't confuse it with the UltraClarity Pro. The REPLFLTR10 has a different physical shape from the UltraClarity Pro BORPLFTR55 / BORPLFTR50. They are not interchangeable. If your fridge uses the Pro filter, see our Bosch UltraClarity Pro BORPLFTR55 filter. You can also browse every Bosch refrigerator water filter we carry.
