A particulate filtration apparatus for exhaust, combustion or other gases includes an enclosure for the output of a flow of such gases, prior to their release into the outside environment. An internal duct crossed by the flow and affected by a perforated conducting plate is kept at a negative electrical potential, for emission and dispersion in the duct of electrons coupled to polluting particles carried by the flow and substantially constituting the particulate, consequently giving them a negative electrical charge. Along the duct downstream of the perforated plate is an accumulation plate, kept at a positive electrical potential, for the attraction and stable adhesion of the electrically charged particles on the accumulation plate. A conducting filament at a negative electrical potential adjacent at least one opening of the perforated plate is a primary source of emission and dispersion of electrons which are coupled to particles carried by the flow.
