Blind Filter – Joe Frex Rubber

Joe Frex Blind Filter – Rubber.

Will fit most machines that use a 58mm portafilter basket

No need to pop out your existing portafilter basket – just place the rubber blind filter in your portafilter basket and use with group head detergent to back flush your espresso machine’s group heads. Simultaneously you should use your group head brush to scrub the group head and surrounding channels.

You’ll be amazed at the coffee residue that builds up in your group head over a short period of time.

How often should you backflush your espresso machine.

Commercial espresso machines need to be backflushed every day with water and depending on how busy you are with group head detergent.

Domestic espresso machines should be backflushed with water after every use and backflushed with group head detergent at least once every week.

Espresso machines need to be backflushed to remove the coffee oils and granules that can build up inside your group head and portafilters, blocking the flow of water and killing the flavour of your coffee. If you follow a good maintenance schedule your coffee will taste better and you will extend the life of your espresso machine.
