A corona-assisted electrostatic filtration apparatus which includes a cathode, an anode filter element located in functional proximity to the cathode, and a means of establishing a nonalternating potential difference between the cathode and the anode which is sufficient to maintain a corona field of ionized gas between the cathode and the anode filter element. The anode filter element includes a porous fibrous sheet material having pores in a range of from about 0.1 to about 100 micrometers, with at least a portion of the fibers thereof being uniformly coated with a metal. Also provided is a method of utilizing such apparatus to remove particulate matter from a gaseous medium.
