Looking for an effective noise reducing mains filter/block

[Thetiminator]

I have a mains conditioner for my main stuff. But I have a few things plugged into the wall sockets that I’d like to isolate away from the main supply to my system.
It’s all rubbish - TV, USB plugs for TV remote charger, Firestick plug etc. So I’m looking for something to plug all the rubbish in to, that’ll a). Not be too expensive (a couple of hundred or thereabouts, I don’t mind 2nd hand) and b). have decent noise filtering on board…
Any recommendations?

Any filter starting from Tacima for around £40 might do the job. But if you’re interested in the deeper exploration of the topic you might find out that small stuff is not in fact the most problematic equipment in the house in terms of the ‘hi-fi impact noise’. Something like washing machine may be way worse.
