This unit is supplied with 4 filter inserts: 2 standard filter bas-
kets (1 and 2 cups) and 2 double-walled filter baskets.
The standard filter baskets have the same prerequisites as the
filter baskets used in the commercial espresso machines. They
have a single base: you can see many small holes when held
against the light. The standard filter baskets are designed for
fresh, self-ground coffee. To grind the coffee yourself, we rec-
ommend using the GRAEF CM 80 coffee grinder. The grind
setting is perfectly matched to the espresso machines. If you
do not have a coffee grinder, when purchasing the ground
coffee please make sure the coffee grind is very fine, just like
that used in the commercial machines.
The double-walled filter baskets are designed for use with
typical, pre-ground coffee from the supermarket.
