EMFs are All Around You, All the Time
Your phone. Your laptop. Your router, and your neighbor's router. The smart TV, the speaker on the counter, the cell tower you can't see from the window.
None of it is going away. So the question isn't how to avoid EMFs anymore. It's how to feel steady in the middle of them.
That's the question Harmoni was built to answer.
Your body runs on electrical impulses. Dr. Martin Pall, PhD, Professor Emeritus of Biochemistry and Medical Science at Washington State University, has published 26 papers exploring how manmade electromagnetic fields may interact with that system.
- 3.8 billionsmartphones, and millions of cell towers to support them
- 200 billionmore connected "smart" devices emitting microwave radiation
- 50,000"wireless" satellites set to blanket the earth in microwave radiation
The Frequencies
You Never Chose
Your WiFi. Your neighbors' WiFi. The smart TV, the baby monitor, the speaker on the counter, the 5G tower down the road. Each one adds its own signal, and together they fill the rooms your family lives in with a field of chaotic, man-made frequencies.
You already filter your water and read the labels on what your kids eat. The frequencies in your home belong on that list too.
- Water filter
- works on what you drink
- Air purifier
- works on what you breathe
- Harmoni Card
- is made for the frequencies in the room
Harmoni was made to help neutralize the chaotic frequencies from modern tech and create healthier environments, for you and the people you love.
200+ Frequencies
in Every Card
Every Harmoni EMF Equilibrium Card is imprinted with the same library of more than 200 frequencies as the Harmoni Pendant. Nothing in it runs on a battery or a chip. Four families make up the core of the library, from the Earth's own frequency up to the terahertz band.
-
7.83 Hz
The Schumann resonance
The Earth's own background frequency, the natural resonance between the ground and the upper atmosphere. Physicist Winfried Otto Schumann predicted it in 1952, and it's often called the Earth's heartbeat.
-
174–963 Hz
The nine Solfeggio tones
A nine-tone scale tied to the old solfège syllables (Ut, Re, Mi, Fa, Sol, La) and used widely in sound and meditation practices today.
-
MHz
Megahertz frequencies
Higher frequencies, measured in millions of cycles per second, imprinted alongside the lower tones.
-
THz
Terahertz frequencies
The band between microwaves and infrared light, measured in trillions of cycles per second.
The nine Solfeggio tones
Tap a tone to hear it.
Tone descriptions reflect how sound and meditation traditions describe each frequency. They are not medical claims. The card itself is silent; the buttons above let you hear each tone.
Meet the EMF
Equilibrium Card
The Equilibrium Card brings the frequency library inside every Harmoni Pendant to the rooms you live in. It's a thin, gold-toned metal card, about the size of a credit card, that sits on a nightstand, a desk or a shelf, or rides along in the car.
Set it down once and leave it there. There's nothing to plug in, charge or update, and your phone, WiFi and streaming work exactly as before.
A Card for Each Room
You Live In
Put a card in the rooms where your family spends its days. Most people start with one room, then add the next.
-
Bedroom
Where phones charge overnight and the baby monitor stays on.
-
Home office
The laptop, the monitor, the router and a phone that never stops buzzing.
-
Living room
The smart TV, the streaming box, the speaker and everyone's devices.
-
Kitchen
Smart appliances, the tablet with the recipe, the speaker on the counter.
-
Car
Bluetooth, GPS, the phone on the charger and every tower you drive past.
Grounded in research
Backed by ongoing, evolving research
Harmoni has been the subject of an internal pilot study exploring how the body responds to everyday electromagnetic environments. We're continuing to invest in research as the science develops.
An open-label pilot evaluation was conducted to assess the efficacy of the Harmoni Pendant in reducing stress and the impact of electromagnetic fields (EMF). The evaluation was conducted by eight doctors from across the United States, spanning specialists in various fields, using Heart Scientific HRV technology, which measures stress and nervous system health.
The pendant was evaluated, not the card. The card carries the same library of 200+ imprinted frequencies.
The preliminary open-label pilot evaluation found:
Inner calm
Heart rate variability increased significantly
Heart rate variability, or HRV, is an increasingly well-researched way to measure how stressed-out or calm someone is.
Lower stress
Designed to reduce feelings of EMF-induced stress
Participants reported reduced feelings of stress from EMFs, along with a greater sense of overall wellness, while wearing the pendant.
Preliminary results from a small, open-label pilot evaluation, not a controlled clinical trial. Individual experiences vary. Before-and-after images are illustrative. The Harmoni Pendant is not a medical device.
What card owners say
Verified buyers on where they keep their cards.
“I love it because I don't have to wear it around my neck or put it on my wrist. I leave it in my car. Protecting myself from EMF's is important to me. I don't like to wear jewelery. The card is perfect. Thank you!”
“It brings some peace of mind having the cards in a few rooms to protect from EMF. We also recently started unplugging the Wi-Fi router at night.”
“I like the card. We keep it in our living room where all of our phones are plus the tv. I feel it is protecting us.”
“I bought an EMF card to keep with my laptop. While I work away it is right there next to the touch pad. I have one in my car and one in my phone wallet as well. Can we ever have too many? I think not with all the EMF around us constantly!”
“I'm very pleased with this purchase! I travel a lot, and now I feel more supported when I'm in other people's homes with extensive wifi or when I'm at work (with innumerable electronics) or even when we're driving through congested areas with so much electronic bombardment. This is great!”
“I like having it near my computer while working. The beautiful gold reflections are calming.”
“Great quality - you can feel & see the metals/materials used. I have one sitting on my lap top.”
“I already owned the pendant for several years. I just decided to get extra for the house, phone, car, computer.”
“I'm very happy to be using these EMF card through out my house and on the go . It gives me a peace of mind I'm using a form of EMF protection. Thank you Harmoni, Mary,FL.”

Questions, answered
Still wondering about something? Email support@harmonipendant.com and a real person will get back to you.
How do I use it?
Set it down in the room where you want it: on a nightstand, a desk, a shelf or in the car's center console. Then leave it there. There's nothing to plug in, charge or update.
What frequencies are in the card?
More than 200, the same library imprinted in every Harmoni Pendant. The core of the library is the Schumann resonance (7.83 Hz), the nine Solfeggio tones (174 to 963 Hz), and families of megahertz and terahertz frequencies. The card has no battery and no electronics, so it doesn't emit sound or a wireless signal.
Where should I put my cards?
In the rooms where you and your family spend the most time. Most people start with the bedroom or the home office, then add the living room, the kitchen or the car.
How many do I need?
That's up to you. One card is a good start for the room you use most. The 2-card pack suits a bedroom and an office, or home and car, and the 4-card pack lets more of your rooms have their own.
Will it interfere with my phone or WiFi?
No. The card is passive. It doesn't block, jam or change the signal from your devices, so your calls, data and WiFi work exactly as they did before.
What is it made of?
A thin, rigid metal card with a brushed gold-tone finish, the Harmoni emblem on the front and an engraved pattern on the back.
Is there research behind it?
The Harmoni Pendant, which carries the same frequency library, was the subject of an internal, open-label pilot evaluation run by eight US doctors using Heart Scientific HRV technology. Participants reported feeling less stressed and a greater sense of overall wellness. The card was not part of that evaluation. It's a preliminary evaluation, not a controlled clinical trial, and we're continuing to invest in research as the science develops.
Is the card a medical device?
No. The Harmoni EMF Equilibrium Card is a wellness accessory. It isn't intended to diagnose, treat, cure or prevent any disease. If you have a medical condition, talk with your doctor.
What if it isn't for me?
Try it for 60 full days. If you're not thrilled, mail it back and we'll refund every penny you paid. Email support@harmonipendant.com to start a return.
How fast does it ship?
Orders ship from our US warehouse within a few business days. The 4-card pack ships free within the US.
