Greenwave filters significantly reduce the amount of DIRTY ELECTRICITY (a.k.a., electrical noise, line noise, EMI) present on the wiring in buildings. This is a direct, effective, and practical way to clean up this type of EMF pollution. The less dirty electricity there is flowing along building wires, the less that will radiate into your environment. The filters plug directly into electrical outlets and power strips. They deploy state-of- the-art EMI filtering technology to “short out” (or shunt) erratic surges and spikes of electrical energy (i.e., dirty electricity), while allowing standard electricity to pass through the filters unimpeded.

How Many Filters Do You Need?

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)
Bedroom,Dining Room,Laundry Room 2 filters (each)
Bathroom,Walk-In Closet 1 filter (each)
Basement,Garage,Tool Shed,Workshop 1 – 2 filters for every 150 square feet

Schools:  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. 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 – 7 filters: $30 per filter

8 or more filters: $28 per filter


Measuring Results

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 guiding the installation of Greenwave filters. It can help you identify significant sources of dirty electricity in your environment and determine the best number of filters to install in each room for optimal results.


Satisfaction Guarantee

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.

    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!

  3. 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!

    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.

    I’ve already got eight and am purchasing more for family.

    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.

    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.

  11. 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!
