Every Electric Toothbrush Runs a Motor an Inch From Your Brain. Only One Shows You the Number.

1EMF, Explained in Two Minutes

EMF stands for electromagnetic field. Anything that runs on electricity gives one off. There are two parts to it, and a meter reads both: the electric field, in volts per meter (V/m), and the magnetic field, in microtesla (µT). Your phone, your router, your charger, and the motor inside every sonic toothbrush all produce them.

• ⚡ Electric field: measured in V/m
• 🧲 Magnetic field: measured in µT
• 🔌 Every motor produces both, including the one in your toothbrush
• 🤐 No leading electric toothbrush prints the reading on the box

• Sound familiar?
• 📵 You keep your phone off the nightstand and the router out of the bedroom
• 🪥 You've never thought about the motor you press to your face, because nobody told you to

2Fields Drop Off With Distance. A Toothbrush Gets None.

Exposure falls sharply with every inch. That's the whole reason the standard EMF advice works: keep the phone off your body, put the router in another room, use wired earbuds. A sonic toothbrush is the one device that advice can't help you with. The motor sits against your jaw. Distance is zero.

• 📉 Move a few inches away and exposure falls off a cliff
• 🎧 You already use distance everywhere else: wired earbuds, speakerphone, laptop on a desk
• 🚫 You can't do it here. The motor is pressed to your face four minutes a day
• 🎯 When distance is off the table, the number on the meter is the only lever left

3What EMF Exposure Does, According to the People and the Research

EMF stops being abstract when the source is pressed to your jaw twice a day. Nobody can honestly promise a health outcome from a toothbrush, and we won't. But what people report, what researchers have measured, and what happens around metal in your mouth are all documented, and worth knowing before you brush tonight.

• 🤕 What people report around powered devices: headaches, fatigue, trouble sleeping, poor concentration
• 🩹 Tingling or warmth in the skin close to the source
• 🦷 Fillings, crowns, or implants: researchers measured small currents induced in dental metal by electric toothbrush magnetic fields, noted as possible discomfort²
• 🧠 Some people feel it more than others. The WHO recognizes EMR sensitivity (EHS) as real and often disabling, cause still unsettled¹
• 📏 All of it scales with distance, and a toothbrush gets none

• Sound familiar?
• 📵 You already keep the phone off your body and the router out of the bedroom
• 🦷 You've felt an odd sensation while brushing and assumed it was sensitivity
• 🤷 You've asked a brand "what does this give off?" and gotten a non-answer

4Two Studies Worth Knowing Before You Brush Tonight

We're not going to bury you in citations. Two are enough to understand why the number matters, and both are from sources you can check yourself.

• 🌍 WHO: symptoms reported around EMF sources are real for the people who have them, cause still unsettled¹
• 🔬 Peer-reviewed: magnetic fields from standard electric toothbrushes induced small electric currents in metal dental work²
• ⚠️ The same researchers noted those currents could produce pain or discomfort²
• 📏 Both point the same direction: at zero distance, a lower reading is the number you'd want

5The PRIMALS Electric: 11x Less Magnetic Field, 30x Less Electric Field

This is the first natural bristle electric toothbrush, and it was engineered for low EMF from the ground up. We put it on the same meter as the leading electric toothbrush and the notable castor oil bristle brush, at the same distance, in the same mode, at the highest intensity, and averaged more than 100 readings each. Here's what it read.

Meter: ERICKHILL RT-100. Same distance, same mode, highest intensity, 100+ readings per brush, averaged. For scale, the international public-exposure reference level for magnetic field (ICNIRP, a scientific body, not a government limit) is 100 µT. Readings vary with meter, distance, mode, and intensity. These are our own measurements, published so you can repeat them.

• 🧲 11x less magnetic field than the leading electric toothbrush, about 9x less than the castor oil brush
• 📉 30x less electric field, same meter, same conditions
• ⚡ Still a full 62,000 movements per minute sonic clean, 5 modes, 3 intensities
• 🐗 Boar bristle for a deeper clean, or 🐴 horse bristle for sensitive gums, same low EMF handle

6A Million People Didn't Switch Because of an Ad

They switched because someone they trusted showed them the brush, and then they showed someone else. Over a million people, more than a thousand clinicians, and a comment section that does the selling for us. That's probably why you're here.

• 👥 Over a million people have switched to PRIMALS
• 🩺 Shared by 1,000+ clinicians with their patients
• ⭐ 4.9 average rating across the range
• 💬 "I never thought about this" is the most common first reaction
