We moved into a house with an old Honeywell electrostatic air filter from the 1980's. It might have worked once, but it definitely didn't work anymore. There was a thin filter in the shaft in front of him, but it wasn't very effective. The smart guys at 3M designed this paper filter to fit perfectly in the ESP chamber. Ours lasts about a year just for heating. Retrofitting technology has rarely worked so easily and so well.
