Your espresso is only as good as the water inside your machine. Hard water and chlorine don't just affect taste — they build up inside your Breville's boiler and pump, shortening its lifespan. These activated charcoal filters remove impurities before they reach your machine, protecting your investment and improving every shot you pull. Compatibility ✓ Fits all Breville espresso and coffee machines using BWF100 filters: Barista Express (BES870XL), Infuser (BES840XL), Dual Boiler (BES920XL), Oracle (BES980XL), BES900XL, BES860XL, BKC600XL, BKC700XL, and additional models with reservoir-mounted filter holders Activated charcoal — removes chlorine & sediment Ultra-fine activated charcoal absorbs chlorine, odors, and mineral impurities before they reach your boiler. Cleaner water means cleaner extraction and a more balanced, aromatic espresso.
