A method, substrate and arrangement for creating a particle collection and/or a particle cleaning of a surface part supporting loose or loosened particles. A piece of flexible sheet material, adapted to, via an electrostatic field strength, collect loose and/or loosened particles, and a support layer tightly cooperating with and supporting the piece of flexible sheet material, where both the piece and support layer are adapted to be air permeable for a cleansing of the particles within the piece of flexible sheet material. A use of generated air streams shall, under an overpressure and/or an underpressure, be allowed to pass through the substrate, in a deionized state, in a direction through the support layer and the piece of flexible sheet material. The piece of flexible sheet material forms a filter unit which is adapted at least for collecting of micro- and nano particles and activatable under an electrostatic field strength.
