Blind filter for backflushing your brew group
A small part that keeps your machine clean and your espresso honest. The blind filter sits in place of the normal basket in the portafilter and lets no water through – so you flush the brew group from the inside and dissolve the coffee oils and residue that build up over time.
Regular backflushing is part of the care routine: coffee oils turn rancid over time and settle as a fine film. Keep the group clear and you taste it in the cup – cleaner, clearer, the way the coffee is meant to be.
