You no doubt have elevated electric fields because of the lack of an equipment grounding conductor ("ground") in all of your cables and going to your junction boxes like outlets and lights and everything. This does increase electric field a lot. There are also some advantages, believe it or not.
The Stetzerizer Filters are still recommended to try. They will not make it grounded, of course, only rewiring and running appropriate grounds by a licensed electrician would be recommended to make that happen properly. But the filters are still recommended - they deal with the "hot" and "neutral" anyways and do not mess with or touch ground. That's how we want it.
You can also shut off circuits with the Deluxe cutoff kit. This greatly, GREATLY will reduce electric fields and is recommended for sleeping areas.
