Breville Dual Wall Filter

A dual-wall filter, also known as a pressurized basket, uses a secondary wall with a single small hole to create backpressure. This makes it much more forgiving for beginners or when using pre-ground coffee, as it helps produce a consistent crema even if your grind size isn't perfectly dialed in.

This 54mm basket is specifically designed for the Breville Infuser (840XL) and the Barista Express (870XL). It will not fit Breville machines that use a 58mm portafilter, such as the Oracle or Dual Boiler series.

Yes, this is an authentic Breville replacement component. Using the manufacturer's original part ensures the correct fit and seal within your portafilter, which is crucial for maintaining proper brewing pressure.

Because it is a pressurized basket, coffee oils can sometimes get trapped between the two walls. We recommend soaking it periodically in a solution of warm water and espresso machine cleaning powder to keep the mesh clear and ensure your espresso doesn't develop a bitter, stale taste.
