The Bosch Ultra Clarity Pro BORPLFTR55 (11032531) is a carbon block water filter cartridge built for Bosch refrigerators, and the same cartridge is also sold under Thermador's REPLFLTR55 and Gaggenau's RA450022 model numbers for their refrigerator lines. It is tested and certified against NSF/ANSI Standards 42, 53, and 401, reducing chlorine taste and odor, chloramines, lead, mercury, cysts, sediment, turbidity, and emerging contaminants covered under the NSF 401 standard. The filter is rated for up to 250 gallons or six months of service, whichever comes first. Confirm the filter housing in the specific refrigerator accepts BORPLFTR55/11032531 before ordering, since Bosch has used more than one filter generation across its refrigerator lineup.
