BOSCH / Cuno 9000 077104 UltraClarity REPLFLTR10 Refrigerator Water Filter

Getting clean, great-tasting water from your Bosch refrigerator starts with having the right filter confirmed and replaced on schedule. The UltraClarity REPLFLTR10 is the confirmed replacement water filter for compatible older Bosch refrigerator models using the UltraClarity Standard filtration system, delivering NSF 42 and 53 certified activated carbon block filtration to reduce chlorine taste and odor, lead, rust, sediment, and other common contaminants. Check the part number on your existing filter before ordering to confirm the REPLFLTR10 is the correct replacement for your specific model.

Why Choose the Bosch REPLFLTR10 UltraClarity Water Filter

The REPLFLTR10 is tested and certified to NSF 42 and 53 standards, targeting contaminants that affect both water taste and health quality at the source before water reaches the dispenser or ice maker. Here is what the REPLFLTR10 UltraClarity specifically addresses:

• Chlorine taste and odor
• Lead and heavy metals
• Rust and corrosion particles
• Sand, sediment, silt, and turbidity
• Cysts and particulates affecting water clarity

FAQs

Is the Bosch REPLFLTR10 the same as 9000077104 or 644845?

Yes. 9000077104, 644845, BORPLFTR10, and 740560 are alternative part numbers that refer to the same REPLFLTR10 UltraClarity Standard filter format. If your refrigerator currently shows any of those codes on the existing filter label, the REPLFLTR10 is the correct replacement to order.

Can I use the REPLFLTR10 in a Bosch refrigerator that currently uses the BORPLFTR55?

No. The REPLFLTR10 UltraClarity Standard and BORPLFTR55 UltraClarity Pro use completely different physical housing designs and are not interchangeable in any way. If your existing filter shows BORPLFTR55, 11032531, or REPLFLTR55, the BORPLFTR55 is the correct replacement for your unit not the REPLFLTR10.

Why does the REPLFLTR10 have such a high gallon capacity compared to other refrigerator filters?

The REPLFLTR10 is rated for up to 750 gallons per cartridge, significantly higher than the 200 to 300 gallon capacity of most standard refrigerator water filters. This extended capacity reflects the UltraClarity Standard filter design used in compatible older Bosch refrigerator models. However the six month maximum service life still applies regardless of gallon count — replace at six months even if the 750 gallon threshold has not been reached.

What is the difference between the Bosch REPLFLTR10 and the BORPLFTR55?

The REPLFLTR10 is the UltraClarity Standard filter for older Bosch refrigerator models, rated for 750 gallons and carrying NSF 42 and 53 certification. The BORPLFTR55 is the UltraClarity Pro filter for newer Bosch 500 and 800 series and select built-in models, rated for 250 gallons and carrying NSF 42, 53, and 401 certification including emerging trace compound coverage. The two filters use different physical housing designs and are not interchangeable.

Why is my water flow slow after installing a new REPLFLTR10 filter?

Slow flow immediately after installation is usually caused by air trapped in the filter or housing during the swap. Running 2 to 3 gallons through the dispenser clears trapped air and carbon fines and typically restores normal flow. If flow remains restricted after flushing check that the filter is fully seated in the housing and that household water pressure falls within the operating range.

Can I use an aftermarket filter instead of the Bosch REPLFLTR10?

Aftermarket filters may physically fit the UltraClarity Standard housing but certification levels and contaminant reduction performance vary widely between manufacturers. Using a filter that does not carry NSF 42 and 53 certification means contaminant reduction claims are unverified. For consistent tested performance use a certified replacement rated specifically for the REPLFLTR10 housing.
