Electrical Interfernace with Herpstat

I was looking at he manual for the herpstat and I noticed it says this: "If possible, route the probe wires so that they are not in direct contact with the 120vac cables going to the heating devices. Preferably leave at least a few inches between the probe wires and the AC lines to avoid cross talk/electrical interferences issues."

I have a couple of split ferrite core filters laying around, any down side to using these to isolate the probes with the herpstat?
