IMPORTANT: DO NOT use cheaper "motor-start" capacitors... Use real X2 EMI caps. If you don't, you may end up with melting filters and fire!! The little blue caps should be Y-class if you decide to include them, as well.
Yowzers! 25uf at 230 volts is 410 watts! That wall wort will go into meltdown. Why not just use the power saver as is? They have a 1 or 2uf cap in them already, optionally you could add a 200pf cap, the led is already there as a bleed down. If you need more than a few uf to filter dirty power either the wiring in your house is suspect or you doing something you shouldn't be doing.

I bought the Greenwave filters to remedy a problem I had with computer equipment doing weird things I couldn't explain and had troubleshot it down to EMI on the line.

The Greenwave filters are hands down the best device out there for cutting it down. What I actually did was at my main breaker (fuse) panel I installed 2x 15 amp circuits as the first breakers where the 2 lines of the split-phase power I have coming into my North American Supply. It's 220 volt but split phase of 110v and 110v. So I have one 15 amp breaker on the one leg and another on the second. I installed 2 plugs on these breakers and put in 2 Greenwave filters on each plug of each of the split phase lines right at the breaker panel and I dropped my incoming off the chart noise down to 104mv as measured by the Greenwave meter. I then bought extra to put one in each room of the house and I managed to get it down to 24mv at each spot in the house. All the random issues I had with my computer equipment rebooting stopped, I swear I feel better (anecdotal, nothing to confirm though) and I swear that we are having less issues with electronic devices in general.

Just finished putting together my own filters, for 25 of them here in the US with parts ran me around a bit over $300. Though my enclosure isn't as neat since it's a power supply box with a pigtail. Went with two x2 caps and the small y class caps to ground. Don't have a meter to measure the reduction on the line yet but noticed my milligause readings on the cornet meter around the house have come down as I plug more in interestingly enough.

really awesome and informative video! I have some curiosities. My application would be when using a generator during power outages. I want a "dedicated" branch circuit protected by a 20A breaker. I work in the powergen industry as a test tech, but our scope is three-phase power, 480V through 27kV, so I'm not "in the loop" with "residential single phase" power. I'm looking for ideas to "hard wire" protect a single branch circuit from my service panel which will supply a "media center". Your explanations of the usage for specific components is very helpful, as I deal with measuring "resistive/capacitive" loads as part of the "test" process. My "grey" area is how to incorporate mitigation regarding "source" power. That's where your video gave me the "?" moment!. Now I want to explore circuits that can lower THD below 10%. If you have any advice, I would GREATLY APPRECIATE a reply!
Well, one thing to keep in mind is that you should not add capacitive loads like these D.E. filters to any circuit if you're running it on generator power.

Have you been able to track down the source of the noise? I would assume the parasitics of the power cables to your house would do a decent job filtering noise by itself, and the noise would be generated more locally. Also, what is the frequency range you are looking at for the noise measurement?
If you are making for example 4 units, the cheapest option maybe to get a bulk quantity of 48, 2.2uf capacitors, and put 12 in parallel in each unit (total capacitance 26.4uf each unit).
@lyra806Hello. You are very knowledgeable on this topic. As you know, the mains voltage has a frequency of 50 or 60 hertz. I need to cut off all noise from 200Hz and above. What size capacitor should be used?
In the US plug were 120v should I look for lower voltage on the EMI capacitors? I got 20 of TEMCo 25uF 370v motor capacitors siting in the garage may save some money on parts
You can use the same ones. Capacitors can be charged up to the rated voltage, but no more. So a 305V cap will work for both 230 and 120V. At 120V, it will just never charge to higher than 120V. Because you're stressing the capacitors less, they may even last longer!
Hi Mike. Great video if you want to DIY, really informative. I went the easy way and bought 4 Greenwave filters. I saw some other interesting stuff and it would be good to read your opinion about the StaticShield - Power Perfect Box. Do you believe it is worth the price for what it says it does? Benefits stated "Surge protection, line conditioning, EMF reduction, voltage regulation, negative harmonics reduction, reduced electrical consumption, equipment longevity, energy savings". Regards!
Hi Scottie. Thanks for the video. Have you done any research on the whole house filters? I'm wondering if it causes the same issue of pushing the symptoms further away from the filter.. Also, does the capacitor between hot and ground and neutral and ground cause any nuisance tripping issues on a GFCI or AFCI protected circuit? Thanks again!
Haven't tried the whole-house filters since my experience showed that they wouldn't be enough due to the nature of the noise. The neutral/hot - ground capacitors shouldn't cause any nuisance trips... unless they fail, of course!
this looks like an easy way to start a fire. imagine someone with mediocre soldering skills (or worse) making 15 of these. i'm almost positive one of them is going to start a fire.
Maybe I missed something, but doesn't the Greenwave filter act as a 'thru' plug (for connecting an appliance), but this one you've built doesn't appear to have an output?
Hi can you please make a tuto on making emi filter starting from 100hz And rf filter and a harmonic filter too Seperately I want to create 3 seperate filters and connect them to my outlet to filter out lots of noise
Is there such a thing that electricity dumps into the capacitor and then we get the filtered electricity from the capacitor direct instead of the load favoring the capacitor.
Could do, but then I'd also need a thermal fuse in case the varistor pops. Then each filter would also be a surge suppressor... But I've got whole-house lightning surge suppression anyway.
Let's say we all had endless amounts of resources and money, would re wiring your house to work with the devices energy usage, eliminate the need for these? Just curious, cus I have read that it's because of all our "energy saving" devices and our outdated fixtures and outlets that causes the backed up energy, am I understanding this rigbt,or did I get lost again somewhere in there and am totally off?
That's loosely correct, IMO. Many appliances these days come with 'energy saving' motors, for example. And they DO save energy - but they're also noisier!
Is a current limiting device in the hot leg required? Was something fuse like on the original circuit board? Not thinking about protecting the device just wondering about keeping it from getting hot in a fault.
The capacitance value will be the same. You can also use the same caps in terms of voltage (305V) since they will just be even more robust at 120V. Or you can go for 250V caps if they're cheaper. Higher V rating on caps just means they can safely handle up to that voltage. Since USA line voltage is about half that in Europe, you're good.
Hi Scotty, Have you checked the voltage across the L and N when you unplug the filter? Chances are it's going to be pretty high for about 5-10 seconds before the resistor discharges it. Not sure if this is a design flaw, but perhaps something that a different resistor would solve to discharge the capacitor faster.
I remember wondering why Greenwave chose that value, because I had calculated the same thing as you... But when I tested it, the voltage had dropped to about 40V after 1s, if I remember correctly. I figured that was good enough. Otherwise it might need to be an even beefier resistor.
Any gamers here please who suffers from input lag because of dirty electricity ??? Any answers or any solutions found for the delay? Does the filters help?
Scottie, let me do another question: Here in Brazil, some people put a capacitor on the fridge and freezer's motors, saying that it will reduce the energy bill. Probably this will not reduce the bill, but in question on DE, putting a capacitor this way could reduce or mitigate the DE gerated by these machines?
Well, unless they are paying for 'apparent power', it won't make a difference in their power bill. Usually, only industrial customers pay for apparent power; everyone else pays only for 'real power' consumed. The second thing is that in most cases, fridges and freezers don't have 'digital' motors - they still have normal AC motors powering their compressors - so they won't generate much D.E. Of course, that's slowly changing, so newer models will produce D.E... But even then, it's a better idea to test for D.E. with a meter and install filters where necessary. D.E. noise is notoriously difficult to pinpoint and reduce, so you'd have to test!
Hello my friend, is this think work without ground connection? Unfortunately In my country in middle east we haven't any ground conection, and anothe question, is it work with 220v ? ,thanks for your answer 🙏
Scottie, is really necessary a ground working in the outlet to the filter work? Here in Brazil we used don't put the ground on houses(bad costume). If it is really necessary, i can do.
Enjoyed your video. Just wondering if there is such a thing as a whole house device (assuming an electrician would be needed for installation), or do individual appliances have to have separate devices plugged into an outlet within their circuit?
There are whole-house systems, but it seems the noise is filtered better with individual units placed around the house. That was my experience, anyway.
Same cap values. The important value in terms of voltage is the cap's V rating, which in this case is fine since the cap must be rated at anything higher than the line voltage - or in your case higher than 120V.
The filters don't consume "real power", therefore your bill does NOT go up at all. And they can improve power factor, but that depends on what kind of loads you're running already.
Most likely, no. I have a 3-phase "pure sine wave" generator and it REALLY doesn't like the extra capacitance. As far as I know, there is no way around this. In fact, Greenwave added a note on their web site telling people not to use their filters when powering from a generator. I talk about the genny problem here: th-cam.com/video/zgH_51KXA6o/w-d-xo.html
Nope. You are only billed for 'real power', and these consume 'apparent power'... It's all about Power Factor: th-cam.com/video/odIl-m-jJr8/w-d-xo.html
@@ScottiesTech Thank you for the response. I'm kind of confused. When I test the G-S plug-ins with my Kill -A-Watt device it shows them using about 0.8 amps. I measured several G-S units and always get the same reading. How come? TIA
@@michaelmasztal7871 It depends on how the Kill-A-Watt gizmo is measuring the power consumed. It's probably fairly basic. Most likely, the addition of large capacitors in the D.E. filters skews the reading it gives. What really matters is 'real' voltage x 'real' current - that's what you're billed for. But with AC, any inductor or capacitor skews those readings. With DC, it's much simpler.
@michaelmasztal7871 Michael, after the filter device has been plugged in for a while, touch it to see if it is warmer than the surroundings. If not then no power is being consumed and the power company will not charge you for having it plugged in, even if you do measure a current. The reason is that the current is not in step with the voltage, i.e., they do not reach their peaks at the same time. They are said to be out of phase with each other. If the filter does warm up then you are paying for the electrical power to make it warm. The warmer it is the more it is costing you.
I keep seeing 15 are needed for an average house but how many are needed for a 1 bed bungalow? Do you use one in each socket in your home or is one in each room as good?
It really depends on the the noisy gizmos in your place (and possibly nearby). I would say maybe 5-10 in your case, but you'd really have to test with the DE meter to be sure.
can I use this model: "C 10uF 305VAC (MKP62 305~x2 106 M) Capacitor" ? 106M instead of 106K. +/- 20% tolerance instead of +/-10%. The price is much better for me.
Could this idea be adapted to clean up the noise from a portable generator? I installed a generator panel in my house, but was always unhappy about the noise level coming from the generator (non-inverting, lower cost portable gen). It would be fantastic to create a whole home filter for this purpose, ideally something with an indicator when the caps are starting to dry/die. Thoughts?
im on the same boat. i have a 9000 watt generator i plug up to my house sound sketchy but i would like to build something similar to this for the generator.
I plan to make a few of these filters using a different enclosure. I was wondering if it is ok to use a plug with a short cord extending 3 to 5 inches from the enclosure. Would this have a negative effect on the performance of the filter?
Watched several of your videos and really enjoying them! Question about capacitor choice: I noticed on ebay and Ali there are much cheaper caps that have the exact same specifications except the P(I assume plate size) is smaller. Does this matter a lot? I assume a larger mass doing the same load will be able to dissipate heat more easily and potentially last longer. Is that the only difference? Thanks!
Yeah, that's the question... It's difficult to choose good caps since there's a lot of garbage out there. I usually don't go for the cheapest ones. If it looks too good to be true, it prolly is. Usually what I'll do is go to a good component provider, check out the specs (including phys. size), and then go back to AliExpress or some similar site and try to find what looks like the same product with same specs, but NOT the cheapest one. I still save money, and so far it's worked out pretty well.
@@ScottiesTech Is there a particular reason you picked the values you did for the safety EMI capacitors? I noticed a tear down video of the greewave revealed one 275k version only. Do you think this config does a better job of filtering or is it overkill? Is higher value better for filtering or is that just for the sake of less overheating chance?
@@Novacasa88 A different cap value will just filter different frequencies. I graphed it and concluded the values in the newer Greenwave filter is better, but the old one will also work. It's not really that big of a difference.
@@ScottiesTech One last thing; Would you be interested and or willing to do a follow up that shows how you analyzed the wave form for your mains power to determine the raw line vs the DIY filter and the Greenwave one (if you still have one). That would be really cool to see. I got an oscilloscope recently and want to learn how to use it but I'm avoiding AC power for a while haha.
Hi Scotty, Awesome videos! Thank you for taking the time and making an effort for us mere mortals to understand some of this stuff. I'm getting heaps of dirty e whenever the home solar inverter is on. My limited equipment has picked up a spike at 15.9kHz all throughout the house (the kids are complaining of a 'thin' noise). What value C and R do I need to make sure I filter out 15.9kHz? My math is probably wrong, but from the values in your diagram, the frequency is f = 1 / (2 * pi * R * C) = 1/(2*3.14*110000*0.0000247) = 0.0578 Hz Also worried about your comment about being careful when running off the solar inverter ("larger capacitance can result in voltage spikes from the genny/inverter"). Can you expand on that please?
I'm not sure there IS a good way to filter inverter noise - at least not with this very basic and relatively inexpensive type of D.E. filter. The extra capacitance will no doubt screw up the solar inverters output since they sort of "adapt" to the AC load on the line. I did a video on the genny/inverter issue: th-cam.com/video/zgH_51KXA6o/w-d-xo.html Shortly thereafter, Greenwave added a warning about this very thing to their web site.
@@NoPlanInSight Oh yeah... It's not an LPF really (in the way you describe) because the 110k resistance is also across live/neutral, in parallel with the 25uF of caps. So, the caps tend to just sink/supply juice to smooth the ripples, and the resistors are just there to discharge the caps when the filter is unplugged. In order to make a good LPF for 15.9kHz, you'd have to be pretty careful because the current flowing through the resister will mean possibly BIG power drops, which won't be very efficient. So you'd need something far fancier than what's in a D.E. filter.
In this case: NO! The value of the resistor needs to be high to slowly discharge the capacitors when the filter is unplugged. With a smaller resistor, the big capacitors will discharge very quickly through the small resistance. But the resistor must then dissipate LOTS of power in a very short time - meaning it will probably explode.
I want to Make this product, to help save money. but ive never done this type of work or project before. Id be willing to purchase the materials if you would be willing to send it to me, Id be willing to paypal you money $$$ if you make one better then the green wave filter or as good
Do you think Chinese can do it super cheap? How do you feel in your house? I am not that familiar with dirty electicity but on contrary with EMF...I do measurement in homes so these filters are necessary? BEcause I get the emf down to safe levels anyways
@@ScottiesTech ok, got it. Thanks for the instruction, I have done this before at university - too easy. Built a railgun, as well - that's now on the list for home projects with my boy 😁🐊
Heya Scottie, firstly thanks for your video which is quite educational. I just moved to Spain from England and its 220v in Spain and 240v in UK England. I am an Ayurvedic Therapist but also am into Electromagnetic Rife Beck EMF Practitioner for Body Health and Cancer Treatment and need to not only earth my non-earthed grid outlets but also to condition the power to avoid any additional frequencies being transmitted into these finite systems for health. do you have any suggestions to buy / build or plans / schematics for something to build as I am desperate to keep health frequencies pure.
Make sure ground currents from a non delta grid aren't polluting your ground line, if so the otherwise excellent practice of earthing will only hurt you and those you treat! I've heard europe doesn't have this issue but it may be country specific. Here in the states they break the law and ground locally to avoid paying for a return line. I live in a forest with widely spaced development and our ground is so bad that sleeping on an earthing mat makes my arthritis nightmarish. It took me weeks to figure out why I felt so bad after setting it up. Dr. Sam Milham has some good books, papers and interviews talking about the issue. Sorry I can't answer your question but I hope this helps!
@@austinkuipers6087 How would one know if their house's ground-line had currents coming from a non-delta grid? (And would this possibly why one would feel an odd electrical sensation when grounded via the socket as opposed to straight to earth, or why there would be a 0.5v difference between earth and ground-socket?)
IMPORTANT: DO NOT use cheaper "motor-start" capacitors... Use real X2 EMI caps. If you don't, you may end up with melting filters and fire!! The little blue caps should be Y-class if you decide to include them, as well.
So i should not include little blue caps if I dont have ground in house ?

I want to create 3 seperate filters and connect them to my outlet to filter out lots of noise
I'm going to buy it and test it to see if it works! filters are very expensive! thanks
What’s the low pass frequency, for the 25 uF X2 cap across the AC mains on this DEF?
Is there such a thing that electricity dumps into the capacitor and then we get the filtered electricity from the capacitor direct instead of the load favoring the capacitor.
i made 5 of these and all together they were drawing 10 amps on 220v why is that ? the wire was getting hot
Why don’t you include a varistor to shunt high voltage transient spikes?
Could do, but then I'd also need a thermal fuse in case the varistor pops. Then each filter would also be a surge suppressor... But I've got whole-house lightning surge suppression anyway.
Let's say we all had endless amounts of resources and money, would re wiring your house to work with the devices energy usage, eliminate the need for these? Just curious, cus I have read that it's because of all our "energy saving" devices and our outdated fixtures and outlets that causes the backed up energy, am I understanding this rigbt,or did I get lost again somewhere in there and am totally off?
That's loosely correct, IMO. Many appliances these days come with 'energy saving' motors, for example. And they DO save energy - but they're also noisier!
Is a current limiting device in the hot leg required? Was something fuse like on the original circuit board? Not thinking about protecting the device just wondering about keeping it from getting hot in a fault.
You could add a fuse, but the original filter didn't have one.
why does the caps need to be 25uF? i have 1920mv on my line, 1 filter results in 1600mv
That's a good value since the capacitors act as a very basic filter.
I have heard certain crystals and minerals are also good at filtering dirty electricity. I think organite is a good one but don't take my word on it.
Will the 25cap set up work in USA? What voltage? Thanks :) love your channel
The capacitance value will be the same. You can also use the same caps in terms of voltage (305V) since they will just be even more robust at 120V. Or you can go for 250V caps if they're cheaper. Higher V rating on caps just means they can safely handle up to that voltage. Since USA line voltage is about half that in Europe, you're good.
Great video and info . But i am in Australia and power here 240 so would i still be using same parts ? or up size to what please. ?
Yup, same components will work there, too.
Hi Scotty,
Have you checked the voltage across the L and N when you unplug the filter? Chances are it's going to be pretty high for about 5-10 seconds before the resistor discharges it.
Not sure if this is a design flaw, but perhaps something that a different resistor would solve to discharge the capacitor faster.
I remember wondering why Greenwave chose that value, because I had calculated the same thing as you... But when I tested it, the voltage had dropped to about 40V after 1s, if I remember correctly. I figured that was good enough. Otherwise it might need to be an even beefier resistor.
Can one large single unit be made that could be tied directly to the house main that would filter the entire home?
No, unfortunately.
Hi, sorry would you help? I bought MKP62 106K 305Vx2 capacitor but they sent me 275Vx2, would that be okey? Thanks a lot
Yeah, it should be okay - as long as the line voltage doesn't go above 275V, which should never happen.
Any gamers here please who suffers from input lag because of dirty electricity ??? Any answers or any solutions found for the delay? Does the filters help?
Thanks!
Scottie, let me do another question:
Here in Brazil, some people put a capacitor on the fridge and freezer's motors, saying that it will reduce the energy bill.
Probably this will not reduce the bill, but in question on DE, putting a capacitor this way could reduce or mitigate the DE gerated by these machines?
Well, unless they are paying for 'apparent power', it won't make a difference in their power bill. Usually, only industrial customers pay for apparent power; everyone else pays only for 'real power' consumed. The second thing is that in most cases, fridges and freezers don't have 'digital' motors - they still have normal AC motors powering their compressors - so they won't generate much D.E. Of course, that's slowly changing, so newer models will produce D.E... But even then, it's a better idea to test for D.E. with a meter and install filters where necessary. D.E. noise is notoriously difficult to pinpoint and reduce, so you'd have to test!
Would it be possible to use smd components and put them in a standard uk plug 🤔
Well, EMI caps of those values are usually hugemongous.
Hello my friend, is this think work without ground connection? Unfortunately In my country in middle east we haven't any ground conection, and anothe question, is it work with 220v ? ,thanks for your answer 🙏
Yes to both: it will work without a ground, and it will work at 220V!
Is this the same for the 60hz/120v here in the US as for other markets with different frequencie/voltage?
D'OH! Forgot to mention that! Yup, the same filter will work on 120V/60Hz.
Scottie, is really necessary a ground working in the outlet to the filter work?
Here in Brazil we used don't put the ground on houses(bad costume).
If it is really necessary, i can do.
No, the ground isn't necessary for D.E. filtering.
Enjoyed your video. Just wondering if there is such a thing as a whole house device (assuming an electrician would be needed for installation), or do individual appliances have to have separate devices plugged into an outlet within their circuit?
There are whole-house systems, but it seems the noise is filtered better with individual units placed around the house. That was my experience, anyway.
How does the capacitor values change for 120V 60 Hz vs 240V 50 Hz ?
Same cap values. The important value in terms of voltage is the cap's V rating, which in this case is fine since the cap must be rated at anything higher than the line voltage - or in your case higher than 120V.
What is more effective to buy in a bad case with the dirty electricity,filters by the type of "greenwave" or is there anything that you can advise?
is this consuming electricity? Is this improving power Factor?
The filters don't consume "real power", therefore your bill does NOT go up at all. And they can improve power factor, but that depends on what kind of loads you're running already.
Can I use these with a non-inverter generator to power electronics?
Most likely, no. I have a 3-phase "pure sine wave" generator and it REALLY doesn't like the extra capacitance. As far as I know, there is no way around this. In fact, Greenwave added a note on their web site telling people not to use their filters when powering from a generator. I talk about the genny problem here: th-cam.com/video/zgH_51KXA6o/w-d-xo.html
What is dirty electricity and for what is it not good?
I did an earlier vid on that: th-cam.com/video/ecwetD2zsms/w-d-xo.html
Beam me up, Scotty
NIce work! Do these type devices consume any energy, I.e., will they cost money on your electric bill? Thanks!
Nope. You are only billed for 'real power', and these consume 'apparent power'... It's all about Power Factor: th-cam.com/video/odIl-m-jJr8/w-d-xo.html
@@ScottiesTech Thank you for the response. I'm kind of confused. When I test the G-S plug-ins with my Kill -A-Watt device it shows them using about 0.8 amps. I measured several G-S units and always get the same reading. How come? TIA
@@michaelmasztal7871 It depends on how the Kill-A-Watt gizmo is measuring the power consumed. It's probably fairly basic. Most likely, the addition of large capacitors in the D.E. filters skews the reading it gives. What really matters is 'real' voltage x 'real' current - that's what you're billed for. But with AC, any inductor or capacitor skews those readings. With DC, it's much simpler.
@michaelmasztal7871 Michael, after the filter device has been plugged in for a while, touch it to see if it is warmer than the surroundings. If not then no power is being consumed and the power company will not charge you for having it plugged in, even if you do measure a current. The reason is that the current is not in step with the voltage, i.e., they do not reach their peaks at the same time. They are said to be out of phase with each other. If the filter does warm up then you are paying for the electrical power to make it warm. The warmer it is the more it is costing you.
I keep seeing 15 are needed for an average house but how many are needed for a 1 bed bungalow? Do you use one in each socket in your home or is one in each room as good?
It really depends on the the noisy gizmos in your place (and possibly nearby). I would say maybe 5-10 in your case, but you'd really have to test with the DE meter to be sure.
can I use this model: "C 10uF 305VAC (MKP62 305~x2 106 M) Capacitor" ? 106M instead of 106K. +/- 20% tolerance instead of +/-10%. The price is much better for me.
Yeah, those should be fine.
how much you want ?
Could this idea be adapted to clean up the noise from a portable generator? I installed a generator panel in my house, but was always unhappy about the noise level coming from the generator (non-inverting, lower cost portable gen). It would be fantastic to create a whole home filter for this purpose, ideally something with an indicator when the caps are starting to dry/die. Thoughts?
im on the same boat. i have a 9000 watt generator i plug up to my house sound sketchy but i would like to build something similar to this for the generator.
Those EMI capacitors will probably never dry/die. They were designed to filter powergrid interferences.
Thanks for the video! How would the schematic look if it is a two pin US plug (no earth)?
The same, but you'd ignore the ground prong and the 2 capacitors that are connected to it.
@@ScottiesTech Thank you very much!
I plan to make a few of these filters using a different enclosure. I was wondering if it is ok to use a plug with a short cord extending 3 to 5 inches from the enclosure. Would this have a negative effect on the performance of the filter?
Nope, that's fine. You can even plug filters into power strips if you want.
@@ScottiesTech Thank you very much!
Hey Scottie, are you selling these filters?
Watched several of your videos and really enjoying them!
Question about capacitor choice: I noticed on ebay and Ali there are much cheaper caps that have the exact same specifications except the P(I assume plate size) is smaller. Does this matter a lot? I assume a larger mass doing the same load will be able to dissipate heat more easily and potentially last longer. Is that the only difference? Thanks!
Yeah, that's the question... It's difficult to choose good caps since there's a lot of garbage out there. I usually don't go for the cheapest ones. If it looks too good to be true, it prolly is. Usually what I'll do is go to a good component provider, check out the specs (including phys. size), and then go back to AliExpress or some similar site and try to find what looks like the same product with same specs, but NOT the cheapest one. I still save money, and so far it's worked out pretty well.
@@ScottiesTech Is there a particular reason you picked the values you did for the safety EMI capacitors? I noticed a tear down video of the greewave revealed one 275k version only. Do you think this config does a better job of filtering or is it overkill? Is higher value better for filtering or is that just for the sake of less overheating chance?
@@Novacasa88 A different cap value will just filter different frequencies. I graphed it and concluded the values in the newer Greenwave filter is better, but the old one will also work. It's not really that big of a difference.
@@ScottiesTech Awesome thanks bro!
@@ScottiesTech One last thing; Would you be interested and or willing to do a follow up that shows how you analyzed the wave form for your mains power to determine the raw line vs the DIY filter and the Greenwave one (if you still have one). That would be really cool to see.
I got an oscilloscope recently and want to learn how to use it but I'm avoiding AC power for a while haha.
this homemade filter will help if there is no ground?
Yes. A ground is not required for the filters to work - altho obviously it's much safer in general!
Hi Scotty,
Awesome videos! Thank you for taking the time and making an effort for us mere mortals to understand some of this stuff.
I'm getting heaps of dirty e whenever the home solar inverter is on. My limited equipment has picked up a spike at 15.9kHz all throughout the house (the kids are complaining of a 'thin' noise). What value C and R do I need to make sure I filter out 15.9kHz?
My math is probably wrong, but from the values in your diagram, the frequency is f = 1 / (2 * pi * R * C) = 1/(2*3.14*110000*0.0000247) = 0.0578 Hz
Also worried about your comment about being careful when running off the solar inverter ("larger capacitance can result in voltage spikes from the genny/inverter"). Can you expand on that please?
I'm not sure there IS a good way to filter inverter noise - at least not with this very basic and relatively inexpensive type of D.E. filter. The extra capacitance will no doubt screw up the solar inverters output since they sort of "adapt" to the AC load on the line. I did a video on the genny/inverter issue: th-cam.com/video/zgH_51KXA6o/w-d-xo.html
Shortly thereafter, Greenwave added a warning about this very thing to their web site.
@@ScottiesTech Thanks Scotty! What about the frequency calculation? 110k and 25uF don't seem to work out for the low pass filter.
@@NoPlanInSight Oh yeah... It's not an LPF really (in the way you describe) because the 110k resistance is also across live/neutral, in parallel with the 25uF of caps. So, the caps tend to just sink/supply juice to smooth the ripples, and the resistors are just there to discharge the caps when the filter is unplugged. In order to make a good LPF for 15.9kHz, you'd have to be pretty careful because the current flowing through the resister will mean possibly BIG power drops, which won't be very efficient. So you'd need something far fancier than what's in a D.E. filter.
Maybe a large isolation transformer to drop the noise off? Those usually don't have that high of frequency response.
Is this the same as those high-priced power conditioners Ford audio work?
Also, how do I determine if my electricity is in fact dirty.
@@MikeG-js1jt Didn't you see the D.E. meter he mentioned at the first of the video?
Thank you, I went back and saw it
Oh, your electricity is dirty...no questions about it.
What do you think about the anti -link* Filters in your country? Which one would you use?
is the resistor better with the least resistance?
In this case: NO! The value of the resistor needs to be high to slowly discharge the capacitors when the filter is unplugged. With a smaller resistor, the big capacitors will discharge very quickly through the small resistance. But the resistor must then dissipate LOTS of power in a very short time - meaning it will probably explode.
@@ScottiesTech
And what resistance did you order resistors for these filters?
@@trolenya 220kΩ, 2W.
I want to Make this product, to help save money. but ive never done this type of work or project before. Id be willing to purchase the materials if you would be willing to send it to me, Id be willing to paypal you money $$$ if you make one better then the green wave filter or as good
Dang, ya lost me.
Should be ashamed of yourself
Do you think Chinese can do it super cheap? How do you feel in your house? I am not that familiar with dirty electicity but on contrary with EMF...I do measurement in homes so these filters are necessary? BEcause I get the emf down to safe levels anyways
and why you need several of them? I thought only 1 is enough to filter whole network of the house.
And where to locate them in reference to the main?
Its impossible
So can I make a large filter and connect to the 100 amp lines at the main breaker?
Not really. It will help a bit, but it's better to use multiple filters placed around the house. It's just the nature of the noise involved.
@@ScottiesTech ok, got it. Thanks for the instruction, I have done this before at university - too easy. Built a railgun, as well - that's now on the list for home projects with my boy 😁🐊
@@taylorrob2 I want a railgun!!!!
Heya Scottie, firstly thanks for your video which is quite educational. I just moved to Spain from England and its 220v in Spain and 240v in UK England. I am an Ayurvedic Therapist but also am into Electromagnetic Rife Beck EMF Practitioner for Body Health and Cancer Treatment and need to not only earth my non-earthed grid outlets but also to condition the power to avoid any additional frequencies being transmitted into these finite systems for health. do you have any suggestions to buy / build or plans / schematics for something to build as I am desperate to keep health frequencies pure.
Make sure ground currents from a non delta grid aren't polluting your ground line, if so the otherwise excellent practice of earthing will only hurt you and those you treat! I've heard europe doesn't have this issue but it may be country specific. Here in the states they break the law and ground locally to avoid paying for a return line. I live in a forest with widely spaced development and our ground is so bad that sleeping on an earthing mat makes my arthritis nightmarish. It took me weeks to figure out why I felt so bad after setting it up. Dr. Sam Milham has some good books, papers and interviews talking about the issue. Sorry I can't answer your question but I hope this helps!
@@austinkuipers6087 How would one know if their house's ground-line had currents coming from a non-delta grid? (And would this possibly why one would feel an odd electrical sensation when grounded via the socket as opposed to straight to earth, or why there would be a 0.5v difference between earth and ground-socket?)
