I don’t see it mentioned above so will augment by sharing that it’s also VERY IMPORTANT to take readings IN the electric outlets with a line noise meter like a Stetzer, Greenwave, or Trifield brand meter and filter accordingly. The new-fangled electric meters FORCED on humanity are contaminating the lines all the way along the wiring into the serviced building and radiating out into the rooms and known as “Dirty Electricity”. It can be filtered but only if you know that you should be measuring and mitigating it. This stuff is like carbon monoxide in that you can’t see, taste, or smell it but it can be measured on a meter and can sicken and kill you.
