My understanding from talking to Icecap is that the filters
are in place, but some units aren't quite up to snuff, or
aggravated by poor grounds, questionable wiring, etc.
I've never had any problems with them generating any type
of interference, when working properly.
Of course, I've also seen them smoking, whining, and buzzing.
But they send you a new one for those reasons. :-)
