There is no "that should have". Everything needs a filter, so what is it you think doesn't need one?

There's a filter on the sky box,and both phones

I think was RobertoS was asking was whether or not you have anything plugged in to a phone socket that *isn't* filtered (whether your ADSL kit is plugged into that socket or not)?

An example with an older relative can be the control unit for a panic/fall alarm.

Another thing people often forget (other than the proverbial sky box) are traditional fax/modems or even fax machines.

Another thought: With the improved weather - does her heating (rads or water) only run during the day? This can be a source of electrical noise. Or even if she's added something recently like a fan or any of the health care related appliances the NHS begrudgingly supplies.
