We buy products that claim to block EMF at retail and measure the same source with and without them. Meters are how we measure — not the story. No sponsors.
Shielding paint, phone cases, pendants, blankets, router guards — the box is a claim, not a measurement. We buy them at retail and run a paired test so you can see whether the number moved.
Meters are how we measure. The product is the only variable. Verdicts come from thresholds we published in advance. First product tests are not published yet.
Every product bought at retail with our own money. No sponsorships, no free samples, no brand paying for a result. When a product passes, its buy link may earn a small commission — but only ever added after the verdict, so a good result costs us nothing to give and can't be bought.
Every verdict comes from a paired before/after measurement — never from the marketing copy. The raw numbers are published next to the verdict.
Repeat readings, controlled setups, documented variance. We don't rely on single-moment measurements.
Full methodology, equipment details, distance notes, and limitations published alongside every result.
We explain what readings mean, what they don't mean, and what practical steps — if any — are worth considering.
No alarmism, no dismissiveness. EMF is a real thing worth understanding — not a crisis, not a conspiracy.
Shielding cases, anti-radiation stickers, and chips that claim to block or "neutralize" what your phone emits.
Shielding paint, conductive mesh fabric, and window film — the products with the strongest physics behind them, tested for whether the install actually delivers.
Necklaces, bracelets, and clothing marketed as personal EMF protection — measured, not assumed.
Bed canopies, shielding blankets, and baby-focused products, tested in the sleeping setup they're sold for.
Mesh cages and covers for Wi-Fi routers and smart meters — including what they do to your signal, not just the reading.
Whether you want to suggest a product to test, ask about methodology, or discuss a partnership — we'd love to hear from you.
