Tier1 RWF1110 Replacement for Bosch UltraClarity Filter (4pk) | Compatible with 9000 077104, 644845, REPLFLTR10, 11034152 | Up to 24 Months Supply

**** The Tier1 RWF1110 refrigerator water filter has garnered a mixed reception, particularly among customers using Thermador and Bosch units. While some users highlighted their initial concerns regarding compatibility, many have found that this aftermarket filter performs admirably in their fridges. Notably, the product comes as a four-pack priced at just over $40—a significant savings compared to the genuine UltraClarity filters, which retail for nearly $80 for a single unit. Installation tends to be straightforward, with many users noting that the Tier1 filters fit well and mirror the dimensions and locking mechanisms of the original filters. Water quality has been praised, with several customers reporting clear and great-tasting water after initial installations, provided the filters were properly flushed to remove any manufacturing residues. However, the reception isn't universal. Some customers experienced significant issues, like leaks and inadequate ice production right after installation. One reviewer notably encountered a flooding incident, urging caution when initially using the filters. But generally, users have reported improved ice production and overall satisfaction after the filter is put to use, underlining the potential effectiveness of this economical alternative. This product stands out as a cost-effective option for those willing to take a chance on a third-party replacement, especially for those using it in Thermador refrigerators. However, potential buyers should weigh the mixed reviews closely and remain vigilant during the initial usage. **
