Carter,
I wonder if that would work? I would think that it is used to filter a noisy circuit that is polluting other circuit's in your home. I don't think you can put X-10 devices after this type of filter because it would block the signals from the rest of the house. Perhaps a filter between the switch's and noisy lights. I also remember reading about the booster lincs helping with some troubled circuits. Anyway talk with Bill and let us know what works.
