EMF stands for electromagnetic fields. They're invisible energy fields given off by anything that carries or uses electricity. Some are natural, like sunlight and the Earth's magnetic field. Most of what we live with today is man-made: Wi-Fi, cell phones, smart meters, Bluetooth and the wiring in your walls. Want the longer version? Read our What is EMF? guide.

Health Canada sets exposure limits for radiofrequency energy in Safety Code 6 which is based on heating caused by EMF. Everyday devices like phones and routers have to stay under them. Research on long-term, low-level exposure is still ongoing. Plenty of Canadians would rather keep their daily exposure down in the meantime. That's your call to make, and we're happy to share what we know.

The usual sources are your Wi-Fi router, cell phones, cordless DEC phones, Bluetooth gear, baby monitors, smart TVs and the smart meter on the side of your house. Living in a condo or downtown? Add in your neighbours' routers and nearby cell towers. An RF meter will show you where readings run highest.

Start with the free fixes. Keep your phone off your body and out of the bedroom overnight. Use speakerphone or wired earbuds for long calls. Put your router on a timer so it shuts off while you sleep, and don't sit right beside it. Distance from EMF is your friend! Our Minimize EMF checklist has more. Blushield is for the part you can't switch off.

No, and we'd rather say that up front. Blushield doesn't block, shield or remove EMF, so your Wi-Fi and cell signal keep working like normal. It's an active device. It plugs into the wall (or runs on battery) and broadcasts a low-level scalar frequency field for about two seconds every 30 seconds. A pilot light flickers each time, so you can see it running. If you want to physically block signals, shielding products like Faraday pouches or shielding paint are a different tool for a different job.

Stickers, chips and pendants are passive. They have no power source. Blushield is active. It's powered, it broadcasts on a set cycle, and a home unit covers an area instead of one phone or one person. The Phi Φ2 Plugin reaches up to 45 m (147 ft) in every direction, through walls and floors. It's the reason we don't sell stickers or pendants.

Yes. There's a human pilot study published in a journal indexed by PubMed Central, plus a poultry farm study and a dairy farm study. We'd rather you read them than take our word for it. Start with the pilot study.

There's no Blushield sticker or phone case. A portable unit goes where your phone goes: in a pocket, a bag or the car cup holder. The W1 Ultimate Watch 5G sits on your wrist. And a home unit covers phone use anywhere inside its range. Either way, keep the phone off your body when you can. Distance always helps. See the portables.

It comes down to two things: how much EMF is around you, and whether you need coverage at home, on the go, or both. Most houses start with a plugin. Condos, downtown homes and places near cell towers usually need a stronger cube. Portables cover you at work, in the car and when you travel. The Product Finder takes 30 seconds.
