Abstract
A filter element for filtration of an air stream includes: a folded filter medium forming a bellows, the filter medium being constructed at least in two layers and having a particle filter layer, an electrically conductive filter layer, and at least one edge band, the at least one edge band being connected to at least one outer side of the bellows. At least one further edge band is connected to an outer side of the bellows. The at least one further edge band is electrically conductive. The at least one further edge band forms a pocket open towards one side.

A filter element for filtration of an air stream, comprising:
- a folded filter medium forming a bellows, the filter medium being constructed at least in two layers and having a particle filter layer, an electrically conductive filter layer, and at least one edge band, the at least one edge band being connected to at least one outer side of the bellows,
- wherein at least one further edge band is connected to another outer side of the bellows,
- wherein the at least one further edge band is electrically conductive,
- wherein the at least one further edge band forms a pocket open towards one side, and
- wherein the pocket is open in a direction of an inflow side or an outflow side of the bellows.
A filter assembly, comprising:
- a filter element for filtration of an air stream, comprising:
- a folded filter medium forming a bellows, the filter medium being constructed at least in two layers and having a particle filter layer, an electrically conductive filter layer, and at least one edge band, the at least one edge band being connected to at least one outer side of the bellows, wherein at least one further edge band is connected to another outer side of the bellows, wherein the at least one further edge band is electrically conductive, and wherein the at least one further edge band forms a pocket open towards one side;
- and
- an electronic unit,
- wherein the electronic unit has a blade comprising electrically conductive material which is formed in a manner complementary to the pocket and is held in the pocket in a form-fitting manner.
