Common mode noise (CM) filters are designed high permeability cores Toroidal or cut cores UU with winding such a way that fundamental frequency flux gets cancelled. While common mode noise gets attenuated.
Differential mode choke are made with two or three separate windings (Three for three phase and two for single phase.) With suitable air gap in magnetic path to avoid saturation. C cut cores or gapped cores distributed air gap cores (Powder iron) employed with suitable winding technology.
Line filters single phase are used to blocking to some extent incoming supply noise to the system or system generated noise are (two types one is common mode noise and differential mode noise) to the supply.
