Here's why the field matters with this device specifically. That motor sits against your jaw twice a day. And unlike a microwave across the room, it gives you no distance at all. Here's the mechanism: field strength falls off sharply the further you are from its source. That's the entire reason a router across the room isn't the concern and why nobody worries about the microwave once they've left the kitchen. A toothbrush removes that variable. Two minutes at a time, twice a day, for years, held in place on purpose. So we measured it. Same meter, same distance, same mode, against the leading sonic brush. In our own testing this handle read 19 times less electric field, and substantially less magnetic field. The second half is the bristle. Nylon degrades at 30,000+ strokes per minute, shedding roughly 3,192 microplastic particles per use, up to 2.3 million a year (ScienceDirect, 2025), into gum tissue 10x more permeable than skin. Real boar bristle has nothing in it to shed. It comes from a brand founded in Hawaii to take plastic out of the everyday things nobody questions. 5,000+ clinicians across the US share PRIMALS with their patients. ✅ Low-EMF engineered, 19x less electric field than the leading sonic brush in our own meter testing ✅ Real boar hair bristles on a glue-free bamboo head, the world's first natural-bristle electric ✅ Sheds no plastic, because there are no nylon bristles in it ✅ 62,000 VPM sonic cleaning, removing 10x more plaque than a manual brush ✅ 5 modes and 3 intensity levels, adjustable mid-brush ✅ 365-day battery on one wireless charge, IPX7 waterproof, smart quadrant timer ✅ 60-day satisfaction guarantee and a 2-year warranty 🎁 Every Bundle Includes: 🤝 FREE gifts with every bundle 🤝 2 FREE boar bristle and bamboo heads in the box 🤝 Wireless charging stand and charger included 🤝 FREE next day shipping, shipped from our California warehouse 🤝 60-day satisfaction guarantee on every order Two heads, the stand, and 60 days to change your mind.
