Hi,
I know, I was hoping there was a filter available that might work for this sort of thing... Alas... It looks like no...

I should have been more clear, I was talking about commercially constructed filters...  I will be adding some filters to my neighbor's items, and want commercial ones, for liability reasons.

But as Dave correctly observed, a conventional commercial filter won't work unless you can bond the chassis of the filter to the chassis of the product. That can be pretty invasive for many user devices.

If you think about it, winding turns of the line cord around a ferrite core is about as non-invasive as you can get. The only thing less invasive is doing nothing. :)
