Kuuleyn Portafilter

This portafilter is designed for 54mm machines, specifically the Breville 8 Series models like the 870 and 880. It features a 3-ear lug design, so please verify your machine's group head diameter and ear configuration before purchasing.

A bottomless portafilter exposes the entire underside of the filter basket, allowing you to see the espresso as it extracts. This visual feedback is the most effective way to diagnose issues like channeling or uneven tamping, helping you refine your technique for a better shot.

Yes, the handle is fully detachable. This makes it much easier to thoroughly clean the portafilter head and ensures you can maintain hygiene without worrying about coffee oils building up in hard-to-reach crevices.

Yes, a filter basket is included with the portafilter. You can use it right out of the box, though some home baristas prefer to swap it out for their own precision baskets if they have a specific preference.

If your grind size, dose, or tamping technique is off, you may experience some spraying or 'spurting' during extraction. This is actually a helpful diagnostic tool, as it shows you exactly where your technique needs adjustment, rather than hiding the problem inside a spouted portafilter.
