When you do this, you impose broadband digital signals on your home wiring - and thus, on the grid-based electric and magnetic fields in the home. If the filters do their job, the chances are good that the Internet signal will be unreadable. If you also have wiring errors in the home resulting in high mag fields, your exposure to noise-like EMF can be very high - this is the central health issue. Best to keep the Internet confined to ethernet cable.
EMF Exposure

I don't know how it goes emissions wise, but it does work a hell of a lot better than wireless. I used it in my previous house as my wife's computer was too far from the router and it provided a strong stable connection. I do recall reading somewhere that it is quite dirty from an emissions perspective thoughHow about using network over the wire (via power adapters like Tenda PH3 AV1000) together with Graham Stetzer Filters ? Could this still be usable and offer less exposure then wifi? Was there any research/has anyone measured and compared GS or other units on risk scale tables like these?
(source: EMF pollution: What you can do to reduce your EMF exposure -- Sott.net )
And here are the measurements:
No doubt how harmful it is. However, in comments under Part 2 video (BTW an interesting youtube channel) someone mentioned using filters together with good result ( a comment from "earthcommedy"):
I've also inquired stetzerelectric.com, they suggested it should work too and one can always return a filter if that's not the case.
So there is still a high possibility that PLE+Filters give an option B between A)Ethernet cable and C) using WiFi. Perhaps a little more digging would make it clear.

Well, I FINALLY got around to ordering a Greenwave DE meter and 15 filters. They cost a small fortune since the 230V international version is only available from their web site, and they're $45 a piece - plus shipping + VAT + customs fees!
The first thing I did was measure outlets all around the chateau. Well... That was an eyeopener.
Most readings were about 200-300, with some hotspots about 500-700 where there are lots of puters. But the top 3 measurements were:
1. Behind Laura's desk: 2000+ (IOW, the meter went off the scale!!!!)
2. In front of Iza's desk: 1400
3. Next to Ark's side of their bed: 900
So, first thing I did was install 3 filters at the breaker panel where the power enters the house (in 3 new outlets - one for each of the 3 phases of AC). I noticed that one of the filters sparked when I plugged it in, and they were all buzzing rather nicely (some more than others).
Then I went around plugging in filters and trying to reduce the readings as much as possible in the nasty areas. Of the Top 3 Winners above, all readings are now down around 60, which is a HUGE reduction. I also noted that while they say to get readings down to as low as 25, the GW meter actually reports "Low Noise" when the reading is 100 or lower. That seems more reasonable anyway, because the "balloon effect" as LQB calls it is a real pain to deal with: lower a reading here, and it spikes over there! It's like playing whack-a-mole.
After the remaining 12 filters were installed, the buzz at the 3 filters by the breaker panel is almost 0 now.
Ark discovered that the dimmers in their room were VERY noisy. Interestingly enough, I have an expensive Legrand dimmer that's electronic and even compensates for different types of bulbs (using it with LEDs), and it is actually very quiet in terms of DE noise produced.
I'm not sure what produced the crazy-high amounts of noise in the Top 3 locations, though. It wasn't anything specific plugged in, so there is something else at work that makes those points particularly nasty. Wiring errors shouldn't be a factor because I did the wiring myself in those locations - so no shared neutrals or anything like that.
I'm still not totally happy with readings in some rooms, so I thought I might need more filters. I've shifted filters around to reduce the higher readings here in our downstairs office, and upstairs in L&A's rooms since we spend the most time in those locations. But some bedrooms are still 120 or so, and I'd like to get that lowered. Obviously, sitting at a puter for hours and hours when the level is 560 is probably more exposure than sleeping where it's 120. And some areas (like the Lodge) still have highish readings and no filters.
But I'm not going to pay $1k for another 15 filters. So, I decided to build my own.
This is the inside of a US Stetzer filter from some years ago that I found on YT:
The 256K single cap is 25uF. That resistor as far as I can tell is totally the wrong size for safely discharging that size of cap when the filter is unplugged. Oh well!
So then I took apart one of our 230V GW filters and the following is what's inside:
Note that the above circuit would simplify to just a single 24.7uF cap and a 111k resistor, both across live/neutral. DONE!
As with the older US Stetzer version, there is about 24.7uF of capacitance in the form of 3 MKP62 305V X2 caps across live/neutral. There are also 2 resistors that add up to 111k of resistance to discharge the caps (1/2 W each, and they're actually 222k, I think - close enough). And finally there are two 220pF ceramic single-layer caps between ground-neutral and ground-live. I measured everything just to be sure, disconnecting caps and stuff so I could get accurate readings.
Well, alrighty then!
I did some calculations, and the cap values actually make sense to me when you consider the capacitance, charge/discharge time, risetime of the noise frequencies, and the max current the filters are rated at (15A).
How I think it works: The caps resist a change in voltage. So, when there's a noisy AC sine wave (dirty electricity), you get higher-frequency spikes or dips above or below the nice clean sine wave. IOW, the sine wave looks jaggedy.
If you have a negative V spike, the cap sources current to bring the voltage back up to it's proper smooth level. If you have a positive spike, the cap sinks current to bring it back down. If you don't have enough filters, the cap becomes saturated. In that case, it could source but not sink current. I think...
The two teeny blue ceramic 220pF caps connect to ground must just dump higher-frequency noise to ground or something? They certainly can't sink/source much current like the big honkin' metalized polypropylene EMI caps can.
Anyway, I managed to hop on AliExpress and find:
1. Power Enhancer Save Energy gizmos for $4 each (I need the box with plug)
2. UK -> EU plug adapters (since the 'Energy Savers' are UK plugs w/ground)
3. A bunch of 8.2uF caps ( 3 x 8.2 = 24.6uF)
4. Some 220k 2W resistors (the 0.5W ones are a bit undersized for my taste)
5. Bunch of 220pF ceramic caps
The CassWave filters will look like this:
When it all arrives from China, I will assemble a test filter and see what happens. Total per-unit part cost: $8 a filter!
I wish I would have bit the bullet and done this years ago...

Bravo Scottie - outstanding! My own feeling is that getting it down to around 100 is good enough except for those that are very EMF-sensitive. You have some major reductions that will make a difference (health-wise) in areas of long-term exposure. This EMF noise exposure is likened to ionizing radiation exposure in that the exposure is cumulative.
In general, dimmers are major noise sources. If you've found a good one, replace the others. The electrician that did much of the wiring in my home had the help of one of my AC mag meters when installing a dimmer switch. His first attempt showed the dimmer working fine but AC mag field went way up (wiring error). He fixed it by verifying with the meter.
The price on these filters is ridiculous - most of the cost goes into the packaging. So good deal on building your own - could be a good business opportunity.
Keep in mind that if electrical loads move around, so can the noise - so its good to spot check occasionally.
I was very interested to see that when I moved filters out of bedrooms and down into the office, the noise upstairs in the bedrooms stayed low! So, you really have to play around and see what works best.
And I'm definitely going to do spot checks - especially when new gizmos are introduced.
Now I just have to wait prolly a few weeks before all the filter parts arrive from China. At this rate, I won't need 16 more filters, so the remainder will be a 'Starter Kit' for the Farm!
This sounds very interesting Scottie! I have just finished reading the Invisible Rainbow by Firstenberg and it has resparke my interest in taking action. Previously in looking at filters(like Stetzers) I found the cost to high. But if I could make some filters, that would be awesome. I justed watched your Scotties Tech.info video on this, and wait with bated breathe the stunnijng conclusion to this clean electricity saga!!
Well, I did a vid on Dirty Electricity:
Next stop: DIY filters... and hope nothing explodes.
After a bit of Chinese mayhem, I finally got all the necessary components to DIY some dirty electricity filters...
Behold the prototype CassWave filter!
Not only did it NOT explode, but according to the GreenWave DE meter, it works just as well as a real GW filter.
Total cost per unit: $17.26 each (here in the EU, I ended up paying close to $60 per GW filter)
Will be releasing a new vid sometime in the next few weeks - as soon as I get the time to build the rest so I can show step-by-step how I made the prototype.

awesome Scottie! I've been looking at the parts, and the 'energy saving' plugs in their US configuration have only two prongs. So that will save me some time and money for buying and installing the 220pF. It'll be like the GS DE filtres then, which don't have a ground prong!Et voila! They work super-well.

Cost from AliBaba would be 322$CAN, approx. 16$CAN/filtre for 20 filtres. My best price from Greenwave, after shipping and taxes was 35U$A/filtre. (27$/filtre + 65$ shipping + 65$ tax). (44$CAN/filtre) All other bundles of Greenwave filtres were 28U$A each. I may be able to get the product from AliBaba with no/little tax as individually the items are a small dollar value.
Wish me luck! Time to buy house fire insurance!!
As I was doing my nightly rounds of news, I came across this article, even though they're mentioning it was "wind turbine syndrome", I suppose it could also be related to the EMF produced by the turbines?
Not sure, I thought it was interesting to share here as the courts ruled in the couples favor (translated from French with DeepL):

Yeah, Greenwave included the 220pF caps to ground, but those don't actually filter DE. I think they just dump higher-frequency noise to ground. I actually considered ditching those and saving some money by getting the EU plug version of the Power Saver thingies, but then I figured what the heck... It can't hurt.
I've wondered about that myself... In Milham's book Dirty Electricity, he talks about that cell tower installation in a school yard. The problem in the end wasn't the GHz signals, but the DE generated by the massive DC power supplies for the cell tower.
Well, we're pretty sure the sound of windmills can be a problem, so it might be two different factors that both cause health issues.
That's the main problem IMO with a lot of this stuff: it's usually never just one thing that's causing a problem. And most studies don't factor in things like diet because the researchers simply don't know anything about it!
