1. A filter device for a water-bearing domestic appliance, wherein said filter device has:
a surface filter with a sleeve shape and
a support structure for said surface filter,
a flow-through filter housing with a filter inlet and a filter outlet,
wherein:
said surface filter is held on said support structure and is held stably by said support structure in a surface filter shape adapted to an outer shape of said support structure,
said support structure has through-flow openings towards said surface filter and a central opening at one end of said support structure,
a first flow path for water leading into said support structure and leading out of said support structure through said through-flow openings,
a second flow path for water leading into said support structure and leading out of said support structure through said central opening at said one end of said support structure,
wherein:
said support structure is designed in a circumferential manner and is formed by support ribs forming or comprising said through-flow openings between them,
said surface filter is attached to an outside of said support structure in such a way that said surface filter covers said through-flow openings and rests on an outside of said support ribs.
