Greenwave Dirty Electricity Filters: 2 Room Starter Kit (4 Filters)

Greenwave EMI noise cleaner have helped our house. Up to 1560mV. Now down to 100mV and 46mV.Thank you.

Great product. Works as described. Recommended. Using the EMI reader I was able to compare before and after results and with the filters installed there was a noticeable reduction in noise.

When I tested Emf levels using the Grenwave filters in my outlets, the Grenwave filters made NO difference. I am about to return them. I used a Latnex triple Axis RF High frequency meter HF - B3 G to test many outlets at my house. The meter did show me that my emfs were high by my cordless phone base, and modem and also when I would download info from the Internet on my tablet, so I feel the meter is accurate when it shows NO Emf reductions using the Grenwave filters at my outlets ( so it wasn't reducing emfs at my house and found no benefit.

I don't know if these do anything to make my home healthier, but they seem to work as directed. I purchased a meter from another company that showed which outlets had dirty electricty, and when I plugged these filters in the measurements went down to "safe" levels.But I don't know if "dirty electricty" is a health hazard or not. I asked an electrical engineer I know, very smart and went to one of the best EE schools in the country, who told me she'd never heard of "dirty electricty." So, hmmmm.A resercher in Canada writes about the health hazards of dirty electricty, but I couldn't find anyone else who does, so I dont' know if this is a scam or a non-threat that's turned into a money maker for two small companies.I still have the filters, and use them, just in case..... Who knows???I gave three stars because these work fine, but for what purpose? I don't know if they are really needed.

I got to admit , and I apologize right up front I thought this was a joke!I have headaches quite often so never give it a thought when they got worse!Anyway I bought the starter pack , and the (TF2) meter more on that later!Got them set up and the readings for the dirty electric came down in that room, hence I bought five more , and with each in proper placement I got the normal readings, and the sleep is better and the headaches are back to just once I awhile!I believe if you live in a state such as I do and you can’t opt out of smart meter , or you live in apt ! You should really take a look at these!It takes some time and placement to get best results, and maybe more of them! But oh so good when you get those readings where the belong!Utility companies should be held responsible for this ! Just saying !

-1 star because they didn't help my sleep (probably not sensitive enough), but +4 stars because Greenwave's owner was VERY generous with his time and helpful when he heard that they weren't helping me sleep. The return policy was honored and I really appreciate that. No idea how they affected EMFs as I don't have a meter.

I have a top-of-the-line McIntosh integrated amp. It was passing a 58db 60hz buzz noise through a pair of very detailed resolving Focal speakers 3in from the tweeters. I thought something was wrong with the amp so I had it checked by an authorized McIntosh technician. The tech said the amp checked out normal and the source of the buzz noise was likely coming from high noise on my AC line coming into the room.So after reading Green Wave product reviews I decided to try the product. Well it worked! mainly.I got 4 or the Green Wave modules along with the Green Wave noise measuring tool. The noise measured by the tool coming out of my AC mains outlets was 178mv (numerically and audibly very noisy).After plugging the 4 modules in the open outlets in my music room the line noise reading at the outlet to my audio equipment went from 178mv (noisy) to 24mv (low noise) -A RESULT!I can still hear 60hz buzz noise coming from my speakers but the spl went from 58db to 34db at 1 in from the speaker. Unlike before, I can no longer hear the noise coming from the speakers unless my ear is right next to the tweeters.So for me and my problem, this product worked and is Highly Recommended. Your milage may vary.

Long story short, I bought a few of these filters from a seller on Ebay as the price was deeply discounted. At the time, I had no meter to test how effective these filters were. However, I can speak about things I observed. I slept better, my dogs sleep better, my refridgerator ran quieter, and I felt a sense of ease in the few rooms where I installed them. Maybe, it was a placebo effect. I did not know.Anyway, I broke down and bought Greenwave's meter and another cheaper meter to measure magnetic fields as I heard these filters can produce those. I did not want to trade one problem for another. I tested my outlets with the Greenwave meter, and I got an AM radio station broadcast coming over the speaker on the meter. I ordered more of these filters. I plugged the filters in, and the radio broadcast stopped. I cannot image my home's wiring acting as a giant antenna is good is good for one's health. I also tested the magnetic fields around all of my filters, and those fields are pretty weak and don't travel more than a few inches away from the filters. I am happy. I also do not think it was the placebo effect I that I have been feeling better based on my testing.
