What does LC filter do?
An LC filter combines inductors (L) and capacitors (C) to form low-pass, high-pass, multiplexer, band-pass, or band-reject filtering in radio frequency (RF) and many other applications. Passive electronic LC filters block, or reduce, noise (EMI) from circuits and systems, and separate, or condition, desired signals.

The RC filter is only useful for small load currents. The LC filters are useful for heavy load currents. Less power dissipated in LC filter. …
How LC filter reduce harmonics?
The using of LC filter in three-phase four-wire system reduces the harmonic problem in the system. This LC filter is depending on value of capacitor and inductor. It is not only reducing zero-sequence harmonics but also reduce other harmonics in the system.
