Method for manufacturing a microbial filter device, comprising the steps of:
- providing a first metal layer;
- providing a side of the first metal layer with a porous metal oxide layer;
- and
- after providing the porous metal oxide layer providing a number of chamber defining structures in the first metal layer that are in contact with the porous metal oxide layer.
Microbial filter device, comprising:
- a first metal layer;
- and
- a porous metal oxide layer arranged on at least one side of the first metal layer, wherein the first metal layer comprises a number of chamber defining structures that are provided in the metal layer after arranging the porous metal oxide layer and that are in direct contact with the porous metal oxide layer.
