Greenwave Dirty Electricity Filter

(14 customer reviews)


Greenwave filters are designed to significantly reduce the level of dirty electricity present on the wiring in homes and other buildings. The less unhealthy dirty electricity there is flowing along building wires, the less that will radiate into your environment.

Filters for the U.S. and Canada are available with 3-prong plugs or 2-prong plugs. Both models include a built-in outlet at their base for plug-through convenience, and are safety certified (UL) and RoHS compliant.

Choose the specific number of filters you want for your home, business, workplace, etc. The price charged per filter will depend on the total number of filters ordered. (Not sure how many filters you will need? See full product description below for general guidelines to estimate your filter needs and for per filter pricing info.)

The effectiveness of Greenwave filters can be measured with Greenwave’s Broadband EMI Meter. We strongly recommend this meter for guiding the installation of dirty electricity filters. It can help you determine the best number of filters to install in each room and where to place the filters for optimal results. It can also help you troubleshoot problems, such as resonance, that occasionally arise during installation.

Greenwave filters significantly reduce the amount of DIRTY ELECTRICITY flowing along the wiring in homes and other buildings. This is an effective and practical way to clean up this type of EMF pollution. The less dirty electricity there is traveling along building wires, the less that will radiate into your environment.



The term DIRTY ELECTRICITY refers to erratic surges and spikes of electrical energy traveling along power lines and building wires, where only standard AC electricity should be. Dirty electricity is ONE of four types of EMF pollution now common in homes and other settings. It is also known as electrical noise, line noise power line EMI (electromagnetic interference), and microsurge electrical pollution.

Dirty electricity is created by modern electronics, appliances, energy-efficient lights, and many other devices that run on electricity. Why? Because many of these devices no longer use standard AC electricity "as is." Instead, they must change or manipulate electrical current in one way or another to operate. For example, many electrical devices must convert standard 50/60-Hertz AC electricity (alternating current) into other forms of electricity [such lower voltage direct current (DC) or higher frequency AC] to operate. And, many devices now draw power from wiring intermittently, in short bursts or pulses rather than continuously. They do this by turning the flow of power to a device "on" and "off" repeatedly, sometimes thousands of times per second.

These processes interrupt the smooth flow of standard AC electricity, creating harmonics and erratic spikes of electrical energy known as voltage transients. Once created, this unusable "dirty electricity" spreads throughout a building and even to other buildings via wiring, power lines, and other means. As it travels, dirty electricity radiates potentially harmful electromagnetic fields (EMF) into environments where we live, learn, work, play, and more.

Dirty electricity can interfere with the proper functioning of appliances and electronic equipment, and more importantly, with natural electrical processes within the human body. Exposure to dirty electricity and other types of EMF pollution has been associated with a wide variety of health problems such as cancer, diabetes, asthma, sleep disturbances, fatigue, skin rashes, tingling sensations, allergy symptoms, headaches, muscle and joint pain, brain fog, memory loss, ADHD/ADD symptoms, depression, anxiety, and more.



Greenwave filters use the latest electromagnetic interference (EMI) filtering technology to significantly reduce harmonics and voltage transients present on the wiring in buildings. This is an effective and practical way to target this particular type of EMF pollution. The less dirty electricity there is flowing along building wires, the less that will radiate into your environment.

The filters simply plug into electrical outlets and multi-socket power strips. They "short out" (shunt) erratic surges/spikes of electrical energy (i.e., dirty electricity), while allowing standard 50/60-Hertz AC current to pass through unimpeded.




  • Easy to use! Simply plug the filters into outlets and multi-socket power strips for immediate results.
  • Built-in outlet for plug-through convenience. Most Greenwave filter models include a built-in outlet at their base. You can plug electronics and other devices into the filters when you need an outlet to access power.
  • Safety certified and environmentally friendly. Greenwave filters meet rigorous electrical safety standards (e.g., UL) and are RoHS compliant. RoHS regulations restrict the use of specific hazardous materials such as lead, mercury, cadmium, and phthalates in electronic and electrical equipment/products.


For best results, we recommend installing Greenwave filters throughout your environment. The number of filters needed will depend on the size of the building or space where you want to install them (e.g., # of rooms) and on the concentration of electronics, appliances, energy-efficient lights, and other electrical devices in each room. Here are some general guidelines to help estimate your filter needs.

Home Environments:
The chart below shows the number of filters typically needed for most rooms within homes. You can use this chart to help estimate the number of filters you may need for your home.

Type of Room Number of Filters
Typically Needed
Kitchen, Family Room, Living Room, Media Room, Home Office 3 – 4 filters
(each location)
Bedroom, Dining Room, Laundry Room 1 – 2 filters
(each location)
Bathroom, Walk-In Closet 1 filter
(each location)
Basement, Garage, Tool Shed, Workshop 1 – 2 filters
per 150 square feet

5 filters per classroom

Business Settings:
2 to 3 filters per 100 square feet

Please keep in mind that these are estimates and provide a good starting place for thinking about the number of filters you will need. For the best accuracy, a Greenwave Broadband EMI Meter is suggested. If you would like help determining your filter needs, please contact us at [email protected] or 1-800-506-6098.



The price charged per filter will depend on the total number of filters ordered.

1 – 3 filters: $37.00 per filter
4 – 7 filters: $36.00 per filter
8 – 15 filters: $35.00 per filter
16 – 19 filters: $34.00 per filter
20 or more filters: $33.00 per filter



The effectiveness of the filters can be measured using Greenwave’s Broadband EMI Meter. Simply plug the meter into electrical outlets to measure the amount of dirty electricity on nearby wiring before and after installing filters. The meter is also an excellent tool for identifying sources of dirty electricity in your environment and guiding the installation of Greenwave filters. It can help you determine the best number of filters to install in each room and where to place the filters for optimal results.



If you are not completely satisfied with Greenwave filters, you may return them to Greenwave International within 60 days of purchase for a refund or credit. A 5% restocking fee may be imposed for returns, unless the return is due to a manufacturer defect in the product or a shipping error.

Plug-in dirty electricity filters are not always compatible with solar energy systems and the storage back-up units they use. Check with your solar system manufacturer before installing Greenwave filters.

Greenwave filters and other dirty electricity filters that utilize capacitance technology should NOT be used in buildings being powered by a generator (for example during power outages). If you have a generator to provide electricity during power outages or at other times, UNPLUG dirty electricity filters while the generator is operating to avoid possible damage to your generator, filters, and/or other equipment, appliances, and systems in your environment. The filters can be plugged back in when your home or building has returned to grid-supplied power and your generator is no longer running.

  1. Betsy Maldonado

    Absolutely a fantastic experience. Kim walked me through all my questions and really stellar customer service. She really cares. This is so rare with companies these days. We love our filters. Placing 2 near the breaker box really dramatically dropped the levels in the rest of the house as well. We did the house first and a few rooms didn’t lower as expected but once two were placed near the breaker it fixed it. I highly recommend. Will have these in every home I own.

  2. Rick Anthony

    Had repeated trouble with some or all of the micro-inverters (1 per solar panel) not reporting their condition / results to the system’s controller, even though they were obviously producing. Definitely a communication problem — ie: interference on the power-line commo between them and the solar system’s controller. Plugged in a Greenwave filter next to the house’s breaker-box, and the problem improved. Plugged in another: Now ALL micro-inverters are reporting, and have been reporting all day every day for 2 weeks. Bought the EMI meter and measured the difference — no filter = over 1900mV noise; one filter = 180mV noise; 2 filters = 94mV noise: this IS more noise than ideal, BUT the resultant Signal-to-Noise Ratio (SNR) is good enough to have solved my problem. So, I am buying 2 more filters (to put on certain circuits inside the house) and see if that gets the noise down into a 25mV-50mV range,

    Thank you so much for developing such a wonderful product. Works exactly as described, very simple process to fix a big problem.

    My husband had a blood pressure that was higher than it should be. We tried everything but couldn’t get his blood pressure any lower. We installed the filters and put the wifi in a faraday cage on a power switch to turn off when not in use. His blood pressure came down to normal. We have gotten rid of our florescent lights, touch lamp and any other thing that raised our dirty electric. Our whole house is below 20. We also got rid of the wifi and hard lined the computer. My husbands blood pressure is fine. I would recommend these filters to anyone. We use the tester to test light bulbs and lamps to make sure we are not raising our dirty electric.

    Some of my rooms were improved 99% ! That’s amazing! Also got rid of all my florescent lights! share with friends next!

  6. Stephanie Andersen (verified owner)

    Good news! I set up my home and office with the filters and on the 1st day in the office, I noticed a great change in my energy levels after 3pm, and was able to continue with enthusiasm till 6pm or whenever my last client left!

  7. Tim Thompson (verified owner)

    I received my order of 3 filters on Saturday. After installation the highest reading in our apartment is now 82. Most are 50 or less. Thank you for all your assistance over these last five years. It has been a pleasure working with you and we could not be more pleased and satisfied with the results using your product.

    Greenwave products and service are both first rate! I have used both their meter and a number of their filters for years. The filters clearly work and are so easy to install.
    In our increasingly electronically saturated world, the issues with radiating electromagnetic fields and their impact on our bodies and health are also increasing. Home solar energy panels with their inverters add a major new source of what is called “dirty” electricity.
    Filters like those Greenwave makes and sells greatly reduce the impact of dirty electricity on the human body. Better sleep is just one major benefit.
    I recently consulted with a homeowner and his renters after they installed a new solar power system and immediately thereafter started experiencing sleep problems. I recommended Greenwave filters. After the filters were plugged in, the sleep problems were solved immediately. The filters work!

    Replaced an analog style washing machine with one of the new “efficient” digitally controlled ones. Unfortunately the washer shares a wall with my solar panel inverter and smart meter on the outside wall. this was causing the washing machine cycling and monitoring sensors to malfunction. It had been repaired several times thinking it was the equipment malfunctioning until it was discovered it was the electricity. We were having to run an extension cord to the other side of the house to get the washer to work properly. Tried various things ferrite rings of various mixes, power conditioners etc. These helped some but did not correct the problem. Tried the Greenwave filter this morning and the washer had a clean run. Will continue to monitor. May consider others elsewhere in the house later but for now this has resolved a big headache.

  12. Jason

    I installed these in my house after using their Greenwave Broadband EMI Dirty Electricity Meter. The rooms that I thought would be bad (because of technology) weren’t, but rooms like my bedroom in close proximity to the outside meter had very high EMI readings. I slept on a Bearfoot Grounding Mattress Panel prior, but I feel like my quality of sleep/wellbeing has improved.

    I live in a 40’s era cottage that has older wiring (open grounds) and before ordering I emailed the company making sure I wasn’t going to create other problems. Gene from Greenwave returned my email and we talked on a Sunday afternoon.

    I couldn’t be happier with my purchase and the level of service from Greenwave!

    I bought a Stetzer meter and both Greenwave and Stetzer filters. The Greenwave filters work a little better than the Stetzer filters based on my tests. I recommend people to buy meters and filters so they can be sure they correct their houses to be safer. I was not aware of the dirty electricity issue until just the last few months. Your health may be suffering for lack of knowledge and action on this issue.

  14. Really Organic

    The owner of the company, Gene is FANTASTIC. I had questions and he guided me through everything on the phone. With his filters and his meter, i lowered the dirty electricity a LOT in my apartment and i can FEEL THE DIFFERENCE. Whew! Thanks, Gene!
