Featuring a dual display for before-and-after filter comparisons and an innovative audio function to listen to EMI, it empowers users to identify and reduce dirty electricity for a cleaner, healthier electrical environment. ## Description Greenwave’s Broadband EMI Meter is a device for measuring the level of dirty electricity (a.k.a. electrical noise, line noise, power line EMI) present on the electrical wiring in buildings. The meter is easy to use. Simply plug it into electrical outlets to find out how much dirty electricity (EMI) is present on nearby wiring. Measurements are presented in millivolts (mV) -- an internationally accepted electrical unit of measure. The meter makes it easy to see and hear the difference dirty electricity filters make in reducing the electrical noise on wiring. “BEFORE filter” and “AFTER filter” readings are shown on the same screen simultaneously, making comparisons easy. The meter includes a special audio feature that allows you to listen to the dirty electricity on your wiring and to hear it decrease as filters are installed. The meter is an excellent tool for guiding the installation of dirty electricity 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. [NOTE: Dirty electricity is erratic electrical energy (i.e., voltage transients) that travels along the wiring in buildings where only standard 60-Hertz AC electricity should be. It is produced by electronics, energy efficient lights, and many other modern electrical devices as they manipulate electrical voltage and/or current to operate. Once created, dirty electricity circulates throughout a building and even to other buildings via electrical wiring and power lines. It radiates potentially harmful electromagnetic fields into homes, schools, businesses, and other settings.] Review: It works . - If I had not purchased this item, I would not know that we were receiving a radio channel through the plug-in next to our bed. It is very accurate and a good value for the money displays easily and is very easy for someone to use. You has no previous experience with electricity. I bought this for an annoying high-pitched noise and found a baseball game playing through the plug-in. This item definitely works and was very helpful in showing the Electrician what was wrong! It also shows when there’s too much dirty electricity coming out of which sockets if you compare all the sockets in your home and tells you what is too high. It was a good purchase for me. Review: Amazing product - This is amazing!!! I actually heard Dolly Parton singing a song when I plugged it into outlet. After putting in filters the noise is gone. ## Features - Measures the dirty electricity (a.k.a. electrical noise, line noise, power line EMI) present on the wiring in buildings. - Easy to use! Simply plug the meter into electrical outlets to get measurements. - Measures a broad range of dirty electricity frequencies (approximately 3 kHz -- 10 MHz). - Makes it easy to compare EMI levels before and after installing dirty electricity filters. - Includes an audio feature that lets you listen to the dirty electricity on a circuit and hear it decrease as filters are installed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MEFVYQD | | Best Sellers Rank | #30,122 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #13 in EMF Meters | | Brand | Greenwave | | Brand Name | Greenwave | | Color | Black, white | | Customer Reviews | 4.5 out of 5 stars 151 Reviews | | Item Dimensions | 5 x 4 x 3 inches | | Item Weight | 8 ounces | | Item dimensions L x W x H | 5 x 4 x 3 inches | | Manufacturer | Greenwave International, Inc. | | Measurement Type | Voltmeter | | Model | Broadband EMI Meter | | Power Source | Corded Electric | | Specification Met | RoHS, UL | | Style | Electronic | | Style Name | Electronic | | UPC | 700987683257 | ## Product Details - **Brand:** Greenwave - **Color:** Black, white - **Item Weight:** 8 Ounces - **Power Source:** Corded Electric - **Style:** Electronic ## Images ![Greenwave Dirty Electricity Meter – Plug-in EMI Line Noise Meter - Image 1](https://m.media-amazon.com/images/I/41DxWwTs52L.jpg) ![Greenwave Dirty Electricity Meter – Plug-in EMI Line Noise Meter - Image 2](https://m.media-amazon.com/images/I/31Yi4EibpmL.jpg) ## Questions & Answers **Q: Will plugging in a filter reduce the readings on other outlets on the same circuit, and/or on other circuits?** A: Yes and this is why the meter is valuable. I have plugged the filter in different locations to test for the best suppression. **Q: Can i use my trifield 100xe instead of this?** A: No. You need a plug in meter. Like the Greenwave meter or an Oscilloscope thx! **Q: Why do I need this device, if all it does is measure dirty electricity?** A: This meter is necessary to determine if you have dirty electricity in your home. Per Greenwave, if this meter measures over 50mv (to me 50mv is acceptable) it is considered to be dirty electricity putting out fields that are unhealthy. If you detect dirty electricity, then you purchase the filters from Greenwave. We had excessive dirty E when measured. Some rooms measured over 600mv. Keep in mind the measurements can vary throughout the day (and appliances operating). We measured one outlet in the bedroom that was approx 600mv, when we plugged in the filter and measured the outlet above it, it dropped below 50mv. Since we now have 2 filters in the bedroom and in other rooms, we are now sleeping better than ever - yes the dirty electricity was indeed interfering with our sleep and thus we are feeling better during waking hours. I hope this helps. **Q: Is there an adapter to be able to check 220V lines i.e. furnace, dryer, water heater?** A: There is a way to do it...but you will have to ignore some electrical safety protocols. A 220 line is simply two 110 lines. Open up the receptacle and use jumpers from one hot line (110) and attach other jumper to ground. Then repeat for the other 110 line. Warning...live electricity...need I say more...careful. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works . *by T***E on June 19, 2026* If I had not purchased this item, I would not know that we were receiving a radio channel through the plug-in next to our bed.

After putting in filters the noise is gone. ### ⭐⭐⭐⭐⭐ Great company...Great device. *by M***T on February 9, 2022* Please read "DIRTY ELECTRICITY" by Dr. Samuel Milham. Then read "EMF*D" by Dr. Joseph Mercola..... Then after that you ABSOLUTELY MUST READ "Invisible Rainbow" by Aurther Firstenburg.... I am an electrician / handy man by day...and a musician by night.....these books changed my life.... And are why I now own this meter. It works really well and being able to actually hear the line noise is pretty cool. Their filters work really well also. Two dropped the Circuit the PC is on from 1800mv down to the low 30s (except on boot up, or when the PC is working hard...then it jumps back up to almost 50). We have all been sleeping much better and did also see a huge improvement in the childrens behavior....not that they were bad kids before...they just don't seem to be quite as...."wired", I guess. If you are worried about EMF and other electrical issues....I also HIGHLY RECOMEND changing ALL of your clothing and bedding to 100% Flax Linen or Whool to help shield you. (very high frequency fabrics, just don't mix the two as they cancel out) ## Frequently Bought Together - Greenwave Broadband EMI Dirty Electricity Meter - Greenwave Dirty Electricity Filters: Mobile Travel Kit (2 Filters) - Greenwave Dirty Electricity Filters: 2 Room Starter Kit (4 Filters) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/44428643-greenwave-dirty-electricity-meter-plug-in-emi-line-noise-meter](https://www.desertcart.sg/products/44428643-greenwave-dirty-electricity-meter-plug-in-emi-line-noise-meter) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-04*
