We buy the products. Meters measure them.
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.
Test products that claim to block EMF.
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 publish in advance, and every published test remains available in Test Results.
Independent
Every product is bought at retail with our own money. No sponsorships, no free samples, no brand paying for a result. A commission link is only ever added to a product that passes (a Works verdict), and only after the verdict is decided — a favorable result cannot be bought, and a Partial, No-effect or Backfires verdict never carries one.
We test in a home lab with consumer meters — the TriField TF2 and GQ EMF-390 — not an accredited EMC laboratory. We publish what the meters showed, the setup, and the limits, so you can judge the numbers yourself.
Data-driven
Every verdict comes from a paired before/after measurement — never from the marketing copy. The raw numbers are published next to the verdict.
What guides every test we publish.
Accuracy
Repeat readings, controlled setups, documented variance. We don't rely on single-moment measurements.
Transparency
Full methodology, equipment details, distance notes, and limitations published alongside every result.
Education
We explain what readings mean, what they don't mean, and what practical steps — if any — are worth considering.
Balance
No alarmism, no dismissiveness. EMF is a real thing worth understanding — not a crisis, not a conspiracy.
The protection products people actually buy.
Phone Cases & Stickers
Shielding cases, anti-radiation stickers, and chips that claim to block or "neutralize" what your phone emits.
Paint, Fabric & Film
Shielding paint, conductive mesh fabric, and window film — the products with the strongest physics behind them, tested for whether the install actually delivers.
Pendants & Wearables
Necklaces, bracelets, and clothing marketed as personal EMF protection — measured, not assumed.
Canopies & Blankets
Bed canopies, shielding blankets, and baby-focused products, tested in the sleeping setup they're sold for.
Router Guards & Covers
Mesh cages and covers for Wi-Fi routers and smart meters — including what they do to your signal, not just the reading.
