Has anybody on the list got a "whole house" mains filter installed
at their QTH?

I work in EMC and this would be a very difficult concept to implement as most
commercial filters are designed to filter against some reference plane
(typically the metal cabinet of equipment).
To successfully filter a domestic supply would either involve a filter that is
designed not to need a significant earth impedance or a very large buried earth
mat.

I would not recommend any commercial filters without seeing the design.
