With your choice of a Regular (spouted) or Naked (bottomless) portafilter you can add versatility to your ROK espresso maker.
Regular portafilters offer great convenience and allow you to split the shot if you so choose.
Naked portafilters provide a view of feedback and insight on the quality of your extraction so you can modify, tweak and test grinds and tamps for the perfect shot.
All portafilters listed are compatible with ROK manual Espresso Makers.
Consider ROK Tampers because precision tools enable precision brewing.
