Breville Bottomless Portafilters Vs Spouted Portafilters
Any Breville espresso machine can use either a traditional spouted portafilter or a bottomless or naked portafilter - you just have to make sure the portafilter you choose is the right size to match the size of your group head. So if you have a Breville Barista Express, you could use either a 54mm bottomless portafilter or a 54mm spouted portafilter. If you have a Breville Dual Boiler, you could use either a 58mm spouted or a 58mm bottomless portafilter.
