Surprised you didn't use the snap on versions. :)

This Corcom filter sound like better idea. It is basically a common mode choke. When you wind two wires, hot and return, on the toroidal core it becomes common mode choke. Such choke presents inductance for common mode signals and no inductance for normal mode signals. It is because in normal mode current flows in both wires in opposite directions and each wire induces magnetic flux in the core in opposite direction. Magnetic fluxes cancel and choke has no inductance. For common mode signals induced electrical noise current is the same in both wires, fluxes add up, and choke presents inductance (hence reactive impedance). The other advantage is that for normal mode (differential) currents choke will never get saturated, since induced magnetic flux is zero.
You can also make simple common mode choke by winding few turns of power cord on large toroidal ferrite.
How can you get inductive reactance without inductance or how you can have inductance when inductive reactance is zero. Common mode choke inductance measured in normal mode configuration will be zero or close to zero. That is pretty much how bifilar resistors are built (same principal) - they impose inductance in common mode but no inductance in the differential/normal mode. It can be easily proven either for common mode mode choke or bifilar resistor by measuring inductance.
Inductors are measured in Henrys. (picoHenrys, nanoHenrys, microHenrys, milliHenrys etc... that is the voltage produced by the instantaneous rate of change in current through a circuit with respect to time. The rate of change of current flow is measured in amperes per second, which is frequency. Put another way, X(L)=2(Pi)(f)L or L=X(L)/(2(Pi)(f)). Inductance (L, measured in Henrys) of the inductor and Pi are constants. Inductive reactance (Z, measured in ohms) is the dependent variable of the variable value of frequency (f, measured in hertz).
