A method of manufacturing a bonded filter material, the method comprising: - providing at least one metallic phase in the form of fibers having an aspect ratio, defined as the ratio between a fiber length and a dimension transverse to the fiber length, comprised between 1 and 10000, wherein the at least one metallic phase is selected among the following: (a) metal alloys comprising 50% in weight or more of copper; (b) a stainless steel. (c) metal alloys comprising 50% in weight or more of silver, and wherein the at least one metallic phase has a fiber length comprised between 1 μm and 10 mm and a dimension (d) transverse to the fiber length, comprised between 0.1 μm and 300 pm, - providing at least one filler phase (FP) in powder form, wherein the at least one filler phase is selected from among the following: NaCl sodium chloride, KCl potassium chloride, KI potassium iodide, K2Cr04 potassium chromate, KN02 potassium nitrite, MgCl 2 magnesium chloride and Na2S04 sodium sulfate, - mixing the at least one metallic phase and the at least one filler phase (FP) to obtain a mixture FBMX of the at least one metallic phase and the at least one filler phase (FP), - placing the mixture (FBMX) of the at least one metallic phase and the at least one filler phase into a forming die , - bonding the mixture (FBMX) of the at least one metallic phase and the at least one filler phase in the forming die into an intermediate bonded filter material (IBFM), - removing the at least one filler phase (FP) from the intermediate bonded filter material (IBFM), thereby obtaining a bonded filter material (BFM), wherein said bonding the mixture (FBMX) of the at least one metallic phase and the at least one filler phase comprises applying to the mixture (FBMX) of the at least one metallic phase and the at least one filler phase into the forming die a pressure from 5 MPa to 350 MPa, and a voltage of 1 V to 150V for a time interval up to 500 ms, preferably from 1 ms to 300 ms, and an even more preferably from 1 ms to 100 ms. - providing at least one metallic phase in the form of fibers having an aspect ratio, defined as the ratio between a fiber length and a dimension transverse to the fiber length, comprised between 1 and 10000, wherein the at least one metallic phase is selected among the following: (a) metal alloys comprising 50% in weight or more of copper; (b) a stainless steel.
