On really bad polluters such as the printer/scanner in the lab I often
use ferrite toroids. I leave the wire a bit longer and run it a few
times through the core. That takes care of hardcore RF noise. Of course
one has to mind the max current and limit the number of turns in order
not to saturate the core. Also, cores are conductive, they must be
isolated and mounted so they can never touch live mains contacts.
