Using Capacitors to Filter Electrical Noise | Arrow
In these cases, a band-stop circuit is used to allow the fundamental power waveform to pass but not the higher-frequency range containing the harmonics. Despite being overall a "low-pass" system (filtering out the higher-frequency harmonics), this band-stop filter still employs capacitors to define the upper limit of the blocked frequency band.

What Is A Filter Circuit
A filter circuit is generally a combination of inductors (L) and capacitors (C).The filtering action of L and C depends upon the basic electrical principles. A capacitor C passes a.c. readily but does not pass d.c. at all. On the other hand, an inductor L opposes a.c. but allows d.c. to pass through it.
