You might check for a medical-grade filter. At least in the US, the
medical-grade
filters are designed so that the earth current is extremely low, like
under one mA.
So, almost all the filtering is differential mode, rather than common
mode. That
might defeat the purpose, but it will keep the earth protector from
seeing any
earth current.
