- Compatibility: These premium 4 Pack BES880 replacement water filters are specifically designed for Breville espresso machines, including models such as Oracle Touch (BES990, Batch 1747 & up), Oracle (BES980, Batch 1814 & er), Barista Pro (BES878), and Barista Touch (BES880, Batch 1801 & er). Please verify your existing filter model or code before purchasing to ensure compatibility. - Enhanced Coffee Quality: The Breville ClaroSwiss water filters utilize activated coconut carbon and ion-exchange resins to improve water taste, enhance coffee flavor, and reduce hardness. This effectively eliminates chlorine odors and other impurities, resulting in a better brewing experience. - Easy Installation: To replace the filter, soak it in cold water for 5 minutes and rinse under running water for 5 seconds. Set a monthly reminder for replacement, insert the filter into the holder until you hear a 'click', then fill the water tank with cold water. Submerge the filter to release any trapped air bubbles for optimal performance. - Usage Tips: The filter is designed with no front or back side; however, it's recommended to position the monthly reminder facing your espresso machine for easy visibility. Ensure all air bubbles are removed; otherwise, water may not pass through the filter properly. Each replacement filter lasts 2-3 months, so regular replacement is essential for consistent coffee flavor. - Practical Applications: Ideal for home baristas who want to elevate their coffee brewing, these filters are perfect for daily use in residential kitchens or small cafes, ensuring that every cup of coffee delivers maximum flavor and aroma.
