Out of curiosity I ordered one , end up buying 5 that good , one for my LED TV 2 for each system.On the right system they are not snake oil.
Smaller plug-in AC Purifiers -- Shunyata, iFi, Puron...something else? What do you like?
I like the Shunyata Venom Defender. It does a good job of reducing noise in my outlets.
I'm wondering if others have tried similar, plug in products — such as the Puron Power Filter or the iFi AC Purifier or something else.
