Grant,
I'm asking, since the noise attenuation graph is the only one you posted.
So if that is the only objective of the filter networks you use, I'm only pointing out that similar, if not better performance can be achived at a fraction of the price. Afterall - those filters can be directly mounted in your mains subpanel, so they don't need an expensive box.
If your filters have other advantages over regular filters - dynamic current limiting springs to mind - why not to post a graph showing that ?
Further, I have no reason to doubt the effects your filters have on various medical equipment, but I'm wondering if those Electrophysiology labs have even tried regular filters on their AC lines, like the one I posted
