A waveform correction filter is connected into an alternating current power line to absorb and remove various forms of power pollution, including high-frequency spikes, surges and other forms of high-frequency oscillations, such as those which result from switching inductive loads on and off. The waveform correction filter of the invention includes a fuse and a coaxial amorphous toroidal inductor connected between a power line and neutral with a low-pass filter connected in series with the fuse and coaxial amorphous toroidal inductor. The filter includes a capacitor, a varistor connected in parallel with said capacitor, and a magnetic core inductor connected in series with each other and in parallel with the capacitor and said varistor. A lamp may be connected in series with the resistor and the magnetic core inductor or across the resistor. Various arrangements are shown for connecting a plurality of the waveform correction filters into single phase or three-phase Wine or delta circuits.
