Blanking filter
Blind sieve insert for the porta filter.
Suitable for all E-61 brewing groups. The blind filter is used for back washing in espresso machines with a magnetic valve. The back washing cleans the brewing head and the shower sieve.
The brewing group should be cleaned regularly, as the oils contained in the coffee quickly become rancid when exposed to heat. This impairs the taste of the coffee and can also have negative health effects if neglected.
