From my experience if the outer metallic enclosure of the filter is not really well bonded to a large lump of metal chassis of the equipment making the EMC racket, preferably at 'ground' potential, they don't do much. Once we cured a load of conducted noise emanating from some equipment simply by scratching a bit of paint off the chassis and using two 10p serrated star washers under a similar filter component. The filter is also needing to be located 'at the edge' of the equipment otherwise noise will simply get reintroduced in to the filtered side. >If so, on what basis might EMC compliance be claimed for such a unit? Ask to see the equipment's declaration of conformity! Good luck.
