Clamp on ferrites (in a 1 turn configuration) are not very effective
at HF.   Not even multiple ones.

Instead try a packaged line filter made by Corcom or Schaffner.
Mount it in a small electrical box from any hardware store.  The filter 
should be located as close as possible to the mirror (NOT at the wall 
outlet).
